Dr. Sailaja is also affiliated with various professional bodies including the Association of Chemistry teachers Indian Chemical Society and the Indian Science Congress Association which reflect her standing in the scientific community.he thesis is divided into five chapters Chapter I is an introduction to water pollution caused by natural and anthropogenic sources particularly arsenic poisoning and its effects on human health animal life plants and materials. The literature review in Chapter II depicts a survey of arsenic in groundwater from various parts of the world and India laboratory and analytical methods of arsenic analysis and various types of arsenic removal technologies that are currently in use as well as the research''s goals and objectives. The research study of adsorbents biosorbents and coagulants as well as the methodology employed in this investigation are covered in Chapter III. With the use of functional factors Chapter IV elucidates the experimental approach for adsorption and coagulation processes. Results and discussion in chapter V pertaining to the characterization of materials used and the percentages of Arsenic elimination were studied with the help of parameters adsorption isotherms kinetics thermodynamics and equilibrium. The efficiency of arsenic removal was reported using Brick powder Multan mitti Iron dust and Chalk power as adsorbents Lemon peel powder Fenugreek powder and Neem bark powder as biosorbents Phaseolus Lunatus Phaseolus Vulgaris Abelmoschus and Coccinia grandis as coagulants. Overall the findings imply that a low-cost water filter media can be constructed that is capable of removing metal ions from groundwater for the use of drinking water at all levels of society.
