Abstract

In order to study the utilization of jackfruit peel waste that has no economic value, activated carbon was prepared from jackfruit peel waste as an adsorbent using phosphoric acid as activating agent under nitrogen flow. The influence of impregnation ratio and activation temperature on the physical and chemical properties of the activated carbon was studied. The physical characterization of the activated carbon was identified by nitrogen adsorption at -196°C and also using Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD). The surface chemistry of the activated carbons was identified both qualitatively and quantitatively using Fourier Transform Infrared Spectroscopy (FTIR) and Boehm titration and pH drift method to determine functional groups on the surface of activated carbon. It was found that impregnation ratio and activation temperature have significant effects on both pore development and chemical surface characteristics of the activated carbon. To study the performance of the activated carbon, Methylene Blue adsorption experiment was carried out. Under variation of initial pH, i.e. 1.5, 6.0, 10.0, adsorption kinetic and adsorption isotherm was investigated. Pseudo-first-order and pseudo-second-order models were used to evaluate the kinetic whether Langmuir equation and Freundlich models were developed to investigate the adsorption isotherm. It was found that pseudo-second-order, Langmuir equation, and Freundlich equation could represent the experimental data well. Methylene Blue is one of cationic dyes so that at pH solution more than pHpzc, the activated carbon will be negatively charged. Ionic interaction between Methylene Blue cation and negatively charge surface of activated carbon would enhance the adsorption
