Rhodamine B dyes adsorption on palm kernel shell based activated carbons

Abstract

Palm kernel shell is a promising candidate as activated carbon precursor due to its granular structure, chemical stability, high mechanical strength and local availability at almost no cost. It can be activated into high porosity carbon in a short time due to its high lignin content, low cellulose content and less fibrous structure. This paper aimed to provide a short summary of various types of palm kernel shell-based activated carbons, the preparation strategies, and the textural properties for water pollutants removal. Besides, a case study on the adsorptive performance of palm kernel shell-based activated carbon for rhodamine B removal from water was included to evaluate its feasibility in the treatment of dyes wastewater.
