Kinetics of Methylene Blue Adsorption on Sulphuric Acid Treated Coconut ( Cocos n ucifiera ) Frond Powder

Year: 2015

Type: article

Abstract: In this study, coconut frond treated with sulphuric acid (SACF) was used as a low-cost adsorbent in removing methylene blue (MB) from aqueous solutions. The kinetics of methylene blue (MB) adsorption onto SACF was described by applying the pseudo-first-order and pseudo-second-order kinetic model with the latter better fitted kinetics data. FTIR analysis showed that carbonyl and hydroxyl groups were involved in the uptake of MB. Mechanisms of MB adsorption were identified as ion-exchange and complexation.
