A novel adsorbent for the removal of chromium form aqueous solution by Acacia Fumosa seed shell activated carbon

In this experimental study, the activated carbon was synthesized by acid impregnation and digestion methods using Acacia Fumosa seed shell. The chromium removal was examined by altering the process conditions like carbon dose, chromium concentration, pH, and temperature and interaction time. The viability of the sorption process was examined using Freundlich and Langmuir equations. Evaluating the isotherm equations, the Langmuir equation shows more concordance compared with Freundlich equation. The feasibility of the adsorption was studied using Lagergren's kinetics equations of pseudo order equations of first and second order equations. Experimental investigation implies that the chromium removal follows pseudo-second order equation and it confines the investigation was subjected to time and concentration of chromium. The temperature effect was checked by chromium with Acacia Fumosa seed shell carbon. The Acacia Fumosa seed shell carbon alone was firmed using Gibbs free energy, enthalpy and entropy equations. The FTIR study of the synthesized activated carbon of before and after spectrum confirms the chromium adsorption. The SEM surface of the superficial layer change of carbon of initial and after chromium loaded state show viable change.
