Preparation of Grapefruit Peel Activated Carbon and Its Adsorption Effect on Cr(VI)

Abstract

In this study, pomelo peel was used as raw material, and a activated carbon was prepared by activation with magnesium chloride and heat treatment, and the adsorption performance of pomelo peel activated carbon (PPAC) was investigated based on different activation temperatures, different adsorption times and different initial concentrations of Cr 6+ , as a way to study the adsorption kinetics of PPAC for Cr 6+ . The results showed that the PPAC obtained at the activation temperature
