Utilization of bivalve shell-treated Zea mays l. (Maize) husk leaf as a low-cost biosorbent for enhanced adsorption of malachite green
In this work, two low-cost wastes, bivalve shell (BS) and Zea mays L. husk leaf (ZHL), were investigated to adsorb malachite green (MG) from aqueous solutions. The ZHL was treated with calcined BS to give the BS-ZHL, and its ability to adsorb MG was compared with untreated ZHL, calcined BS and Ca(OH...
