Abstract

Bioremediation is effective for reclamation of heavy metals from contaminated water because it is economic viable and environmentally friendly. In this study, citric acid chemically modified Coriandrum sativum leaves (CACSL) and Petroselinum crispum leaves (CAPCL) were used as biosorbents. This study investigated both adsorption capacity and adsorption efficiency of CACSL and CAPCL by eliminating Pb2+ and Cu2+ ions from prepared metal solution. Both biosorbents were distinguished by Fourier-Transform Infrared Spectroscopy (FTIR). The concentrations of metal ions were determined by Atomic Absorption Spectroscopy (AAS). Batch sorption studies were carried out by using different biosorbent dosage (0.04g – 0.10g), contact time (30min – 120min) and initial metal concentration (10ppm – 40ppm) at pH 4, 25℃, 200 rpm and 40
