Sabde , ShrirangVishwanth (2013) Management of Industrial Solid Waste by Utilizing as an Adsorbent for Methylene Blue Removal. MTech thesis.
An adsorbent has been prepared from spent pot liner, an aluminum industry solid waste. Surface activation of SPL is performed using leaching process. Leaching process employed variation factors like L/S ratio, acid-alkaliconcentration. Optimized leaching process is used for further adsorption study. Investigation has been made to explore the possibility of this adsorbent for liquid phase adsorptive removal of methylene blue (MB). Comparative study of raw and activated adsorbent has been performed to investigate effect of activation process. Optimization and designing of experiment is performed using response surface methodology. Initial dye concentration, adsorbentdose, contacttime, pH, temperature were found as significant factor for adsorption of MB dye. Optimization of raw and acidic-alkali treated SPL shows that treated SPL is effective and economical feasible compared to raw SPL.Adsorption isotherms study Experiment yields excellent fits for raw SPL adsorption asRedlich-Peterson>Freundlich>Langmuir>Temkin. Similarly, this order changed for acid-alkali treated SPL as Temkin>Redlich-Peterson >Freundlich>Langmuir.
