Title

Heavy Metal Removal From The Wastewater By Using Low Cost Adsorbent

Abstract

Heavy metal toxicity because of industrial waste has been a threat to the environment for the past several decades, particularly within the developing countries like India, China and Kingdom of Thailand wherever price effectiveness of the removal method may be a major factor. This industrialization has not only brought development and prosperity however eventually disturbed the system. One of the impacts is visible; in kind of pollution. Within the gift study heavy metal contamination of water bodies has been mentioned. Effluents from sizable amount of industries viz., electroplating, leather, tannery, textile, pigment & dyes, paint, wood process, crude purification, photographic material production etc., contains vital measure of heavy metals in their waste. The traditional strategies of treatment of heavy metal contamination includes chemical precipitation, chemical reaction, natural action, membrane separation, reverse osmosis, electro chemical analysis etc. These strategies square measure expensive, energy intensive and sometimes related to generation of hepatotoxicity byproducts. Thus, the adsorption has been investigated as a price effective technique of removal of serious metals from waste. In the present study numerous low cost adsorbent has been reviewed as an abatement of serious metal pollution from lignin, iron (III) hydroxide and red mud, low husks, feather palm waste, tea plant waste, sugar beet pulp, battery trade waste, ocean nodule residue and grape stalk wastes are explored for their practicableness to get rid of hepatotoxic heavy metals from contaminated water. These adsorbent includes materials of natural origin like zeolites, clay, sphagnum moss and polysaccharide square measure found to be an efficient agent for removal of toxic serious metals like lead, Cd, Zn, Cu, Ni, Hg, Cr etc. aside from these numerous agricultural wastes like rice husk, neem bark, black gram, waste tea-coffee, walnut shell, coconut coir, coconut husk, bagasse etc. were also established as a potent adsorbent for heavy metal removal. Beside that low cost industrial by product like ash, blast furnace sludge, waste slurry.

Key Words
