Abstract:In the last few years, low-cost adsorbent materials for the removal of heavy metals (Pb, Cd, Mn and As) from contaminated water, have been successfully studied. The purpose of this paper was to compare the different types of bio-sorbent materials from agricultural and wood residues and the factors influencing the adsorption process in their removal capacity of heavy metals in aqueous means, such as duration of contact, the effects of pH, and temperature. This way, relevant information is presented, such that i… Show more
