Modified Mangosteen Shell in the Removal of Hg (II) from Aqueous Solution-Isotherm and Kinetic Studies
An activated carbon was prepared from an agricultural waste mangosteen shell by chemical modification (BTMC) and removal efficiency was tested using aqueous solution of Hg (II). The functional groups and surface morphology of BTMC were analyzed using FT-IR and SEM studies. Commercial activated carbo...
