Simultaneous removal of lead and cadmium ions from simulant and industrial waste water: using Calophyllum Inophyllum plant materials as sorbents.

NOVELTY STATEMENT: The merit of this investigation is that simple and effective bio-sorbents based on Calophyllum inophyllum plant materials with high sorption capacities, are developed for the simultaneous removal of the toxic Pb2+ and Cd2+ at neutral or nearly neutral pHs. These sorbents are successful in water remediation of Pb2+ and Cd2+ ions from real effluents from industries. These findings have great significance as the identified bio-sorbents are simple, effective and renewable in extracting highly toxic lead and cadmium ions from the effluents from industries or polluted water.
