The Use of Activated Carbon Prepared from Jackfruit (Artocarpus heterophyllus) Peel Waste for Methylene Blue Removal

Abstract

Jackfruit peel waste which has no economic value has been utilized for activated carbon preparation. The preparation of the activated carbon was carried out using chemical activation with phosphoric acid as activating agent. The impregnation ratio was 4:1 (g H3PO4/g raw material) and semi carbonization process was conducted at 200oC and followed with carbonization at 550 o C. The applicability of this adsorbent for organic pollutant removal purpose was then evaluated using Methylene Blue adsorption in aqueous solution. Langmuir and Freundlich equations were used to model the adsorption equilibria data, and pseudo-first order and pseudosecond order models were used to correlate the kinetic data. The Langmuir equation gave better correlation for methylene blue adsorption onto activated carbon produced from jackfruit peel. The kinetic adsorption data follows pseudo-second order model.
