Adsorption of Lead Using Jackfruit Peel Activated Carbon

Abstract:

Adsorption using activated carbon that decomposed from agricultural waste has been proven to be effective in removing heavy metals in wastewater. This study was carried out to investigate the adsorption of heavy metals wastewater (Lead) using activated carbon that synthesized from the fruit waste which is jackfruit peel. The efficiency of jackfruit peel activated carbon in removing lead from wastewater has been compared to the commercial activated carbon. Result shows that the commercial activated carbon gave better result as compared to jackfruit peel activated carbon (98% of lead removal for commercial activated carbon and 80% of lead removal for jackfruit peel activated carbon). This can be explained from the characteristics of the activated carbon where the commercial activated carbon has a very well develop pores structures in contrast to jackfruit peel activated carbon. In term of isotherm and kinetic study, the Freundlich isotherm model is better fitted in equilibrium adsorption isotherm for jackfruit peel activated carbon and it is favorable adsorption condition. For commercial activated carbon, the Langmuir isotherm is better fitted to the adsorption of lead and monolayer adsorption capacity was found. The experimental data fitted very well the pseudo second order in kinetic model for both activated carbon where the adsorption controlled by chemisorptions.
