...Clays and Clay Minerals, Vol. 49, No. 5, 410–432, 2001. BASELINE STUDIES OF THE CLAY MINERALS SOCIETY SOURCE CLAYS: INFRARED METHODS ´ JANA MADEJOVA AND PETER KOMADEL Institute of Inorganic Chemistry, Slovak Academy of Sciences, SK-842 36 Bratislava, Slovakia INTRODUCTION Infrared (IR) spectroscopy has a long and successful history as an analytical technique and is used extensively (McKelvy et al., 1996; Stuart, 1996). It is mainly a complementary method to X-ray diffraction (XRD) and other methods used to investigate clays and clay minerals. It is an economical, rapid and common technique because a spectrum can be obtained in a few minutes and the instruments are sufficiently inexpensive as to be available in many laboratories. An IR spectrum can serve as a fingerprint for mineral identification, but it can also give unique information about the mineral structure, including the family of minerals to which the specimen belongs and the degree of regularity within the structure, the nature of isomorphic substituents, the distinction of molecular water from constitutional hydroxyl, and the presence of both crystalline and non-crystalline impurities (Farmer, 1979). The interpretation of the absorption spectra of the Source Clays in the middle-IR (MIR) region (4000– 400 cm 1) given here follows those of Farmer and Russell (1964), Farmer (1974a, 1979) and Russell and Fraser (1994). In addition, reflectance spectra in the near-IR (NIR) region (11,000–4000 cm 1), where overtones...

...The different types of clay minerals can be further differentiated into sub-groups according to the degree of ordering and type of isomorphic substitution (Luis and Mercedes, 2011). Three main groups are Kaolinite group, Illite group, Smectite group. Kaolinite has a structure which consists of one silica sheet and one alumina sheet bonded together into a layer about 0.72nm and stacked up repeatedly (Figure 4a).Numerous hydrogen bonds held the layers together and results into a tightly stacked layers.Illite consists of repeated layers of one alumina sheet in between two silicate sheets (Figure 4b). The layers are 0.96nm thick and held together by potassium ions (Muni, 2007). Montmorillonite has a structure similar to Illite, however, the layers are held together by weak van der Waals forces and exchangeable ions (Figure 4c). Water can freely enter the bond and separate the layers in montmorillonite, resulting in swelling. Montmorillonite ids often dubbed a swelling or expansion clay (Muni, 2007). The Subracent alluvial soils of Peninsula Malaysia contain Kaolinite, Gibbsite, Goethite, Anatase, Mica, Chlorite and mixed layers. Dominating with more that 50% of this clay fraction in some cases is the most important mineral, Kaolinite. The buffering action is controlled by Kaolinite at pH above 5.5. The formation of gibbsite and anatase is dependent on texture and drainage conditions (Shamshuddin, 1986) ...

...Social enterprise is an enterprise which help to improve the human life style by teaching them skill as well as the environment but without caring if it can earn profit or not. Although this seen no profit to the investor as if they believe doing this can maximize their utility by helping the weak can further their capacity to realize their social and environmental goals. The social enterprise that we choose for this assignment is Eden Project. The project is located at Kaolinite pit, which is 2 kilometres from the town of St Blazey and 5 kilometres form the large town of St Austell, Cornwall in the United Kingdom. The project since started at January 1995 because of the hole it give the owner of the project an idea that they need a large place for their plant, so in 1996 they began to design the Eden, the works started in 1998, then finally paid off the funded in 2000 as well as let the visitor visit how they build Eden and the first plant come in the Eden, at last Eden open the door at 2001. The motivation of the Eden Project is that they wish to explore ideas and innovations that can help human being to tread lighter on the planet. How they save the environment? First they cutting the carbon that their produce by planting thousands of plants and also limited the energy use so the building of Eden is special as most of the light come from sunlight. Next they change the waste into useful item with the process of measure, reduce, reuse, recycle and reinvest, for example they...

...University of San Carlos Nasipit, Talamban, Cebu City, Philippines CERAMIC INSULATORS: AN IDEAL FOR ELECTRICAL SAFETY By: Kirby Emmanuel C. Oraiz Frank Joseph P. Ruiz Ramel Joseph A. Derecho University of San Carlos Talamban Campus Nasipit, Talamban, Cebu City, Cebu INTRODUCTION: Science and technology are in continuous development. This leads to ever more demanding and intelligent technology. The demands made on modern materials are increasing with the same dynamism. The features that are demanded include greater strengths for material-saving constructions, lighter components for energy saving, higher quality for more security and longer service life. After all, cost-effectiveness plays a crucial role. Ceramic materials have in the past made an important contribution to this process of innovation. Requirements for the successful application of ceramics include constructions that are appropriate to the materials and the manufacturing processes, as well as appropriate applications. The point is not that common materials can be displaced, but rather that customised products allow completely new solutions. In order to make intelligent and effective use of the properties of ceramics, it is not sufficient simply to take an existing structural component and to replace it in every detail with a ceramic part. A drawing of the component used so far, however, together with a great deal of supplementary information, can show the way to the mass-produced ceramic component...

...CHAPTER ONE INTRODUCTION 1.1 BACKGROUND OF STUDY Removal of heavy metals such as cadmium, lead, nickel, chromium and copper from aqueous solution is necessary because of the hazardous effect it does on the environment ,thereby making environmental protection important, however waste solutions containing heavy metal elements need treatment systems that can remove these contaminants effectively (Harvey and Chantawong, 2001). Frequent appearance of these metals in waste streams from many industries, including electroplating, metal finishing, metallurgical, tannery, chemical manufacturing, mining and battery manufacturing. This problem has received considerable attention in recent years, primarily due to the concern that those heavy metals in waste streams can be readily adsorbed by marine animals and directly enter the human food chain, thus presenting a high health risk to consumers (Lin et al., 2000). A number of technologies for treating contaminated effluents have been developed over the years. The most important of these techniques include chemical precipitation, filtration, ion- exchange, reverse osmosis and membrane systems. However, all these techniques have their inherent advantages and limitations in application. In the last few years, adsorption has been shown to be an alternative method for removing dissolved metal ions from liquid wastes (Bayat, 2002). The removal of heavy metal ions from industrial wastes using different adsorbents is currently...

...SEPERATION PROCESSES II DESIGN PROJECT COAGULATION & FLOCCULATION PROCESSES IN THE PRODUCTION OF POTABLE WATER SUBMISSION DATE: 14 August 2012 COURSE COORDINATOR : Dr. Netatollah Rahmanian GROUP MEMBERS’ NAMES: Derek Lai Chai Zern 14233 Derek Lai Chai Zern 14233 Sean Suraj Jeremiah 14286 Nabila Syahira Bt Azizuddin 14295 Hazwan Farid B Muhammad Puzi 14382 Karrthik S/O Subramaniam 15450 Kiveeyashini D/O Govindasamy 17252 INTRODUCTION Human settlements have always been centred around sources of clean drinking water. As the population increases and the quality of fresh water declines, it has become an engineering challenge to supply sufficient potable water to the meet demands. Of the many unit processes and operations used in water treatment, coagulation and flocculation required a unique combination of chemical and physical phenomena for producing water acceptable for human consumption. Aggregation of fine particulate matter into larger particulates by the use of coagulation and flocculation facilities permits cost-effective removal in subsequent solid separation processes. Particulates inorganic origin such as clay, silt, and mineral oxides generally enter surface water by natural erosion processes and can decrease the clarity of the water to an unacceptable level. Organic particulates, such as colloidal humic and fulvic acids are a product of decay and leaching of organic debris and litter which have fallen in the water...
