Description
Summary:The natural aquatic environment is contaminated by domestic and industrial effluents containing toxic heavy metals, dyes, and acids. These effluents are obnoxious, carcinogenic, and non-degradable; therefore, these toxic substances must be removed from the aqueous system to overcome society's sustainability problems. There is a need to develop low-cost sorbent materials for multiple pollutants. This work deals with the use of Momordica Charantia leaves (MCLs) as a biosorbent for the removal of hexavalent chromium [Cr(VI)] and methyl orange (MO). The formed biosorbent was characterized using SEM and EDX. The Freundlich isotherm and the pseudo-second-order kinetic models are better fitted for Cr(VI) and MO. The maximum uptakes for Cr(VI) and MO were 161.29 mg/g and 64.12 mg/g, respectively. This study provides insight into using naturally derived sorbent materials for the environmental remediation of multiple industries.
