ABSTRACT:
Lead, a heavy metal, is a well known
contaminant in water and has been reported to cause serious health implications
to humans, animals, and plants. One of the processes for heavy metal
remediation of contaminated water is chemical precipitation. In this present
work, chemical precipitation of lead from a contaminated aqueous matrix by
chlorides, carbonates, and sulfates of sodium and calcium was compared to lead
removal by molecular sieves and biomaterials (fishbone, grape and spinach). The order of lead
removal from 1400 ppm of lead solution is sodium chloride (31%) burnt
grape (83%) s ground (99.71%)
