Sequestration of Arsenate from Surface Water Using Chemically Activated Carbon of Black Velvet Tamarind Fruit Shell

Abstract

Chemically activated carbon of BVT fruit shell was investigated for its potential adsorption functionalities to remove As (V) from surface water in a batch system. The AC showed maximum removal efficiency of approximately 75% depicting Qmax of 0.00018mg/g at an initial sorbate concentration of 0.016mg/L, a contact time of 26min, and a carbon dosage of 1g. The sorption isotherm studies revealed a better fit for Langmuir isotherm. Hence, a homogeneous monolayer surface adsorption process has taken place.
