Removal of Heavy Metal Mn+2 by The Adsorbent Wollastonite and Effect of pH

Abstract

Water, no doubt, is the first and foremost legitimate friend of living beings on the earth. Toxic heavy metals have been a chief reason of water pollution. Several unfortunate accidents due to heavy metal contamination in aquatic environment stepped up the awareness about heavy metal toxicity and attracted attention towards their studies. Out of these Minimata tragedy in Japan due to mercury poisoning (1953-1960) and Itai disease in Japan due to cadmium toxicity (1947) are immerable. Waste containing metals may come out of a variety of separate operations such as chemical, metal processing, electroplating, metal polishing, metal cleaning, paint manufacture, battery manufacture etc. The source of wastes in metal processing is quite in good number and also highly variable, both in quality and quantity. Metals can be had in source as particle of pure metals in suspension to metal ions and complexes in solution. In the present study the adsorbent wollastonite is used to remove Mn (II) from the water of Sai river and also studied the effect of pH.
