Adsorption behavior of activated charcoal and used battery cell carbon as composite for removal of cadmium ion from aqueous solution

Abstract

To investigate the adsorption behavior of blend activated charcoal and used battery cell carbon for removal of cadmium metal ion, batch adsorption study was used. Batch study for the expansion of parameters such as pH, initial metal ion concentration and adsorbent quantity were utilized. The characterization of the adsorbent samples was done by technique Fourier Infra Red Spectrum (FTIR) and Scanning Electron Microscope (SEM). Adsorption data were computed by Langmuir and Freundlich isotherms. Kinetic data was well explained by Pseudo second order equation, Intra-particle diffusion and Elovich first order equation. Maximum adsorption efficiency was observed to be 75% at 50:50 ratios of activated charcoal and used battery cell carbon. Purpose of blending activated charcoal and used battery cell carbon reduce the consumption of activated charcoal as it is very costly to use for commercial purposes.
