The chemical composition of industrial wastewater is complex which requires complicated chemical processes before its discharge to environment. In this study, industrial wastewater is used to systematically evaluate the adsorption properties of 15 heavy metals using Copper modified activated charcoal (MAC) as an adsorbent. The MAC is derived from locally available bamboo species named Gigantochloa genus. The adsorbent was prepared by CuCl2·2H2O impregnation with HCl activated bamboo charcoal. The physicochemical properties of MAC were characterised by FTIR, XRD, SEM, EDX and BET. The collected industrial wastewater sample was spiked with inductively coupled plasma spectrometry standard solution prior to the performance tests. In addition, we have compared the adsorption performance of commercial activated charcoal (CAC) with MAC. The adsorption tests were conducted at different contact times, three different pHs and four different concentrations of heavy metals. The results revealed the adsorption of most elements in the multi-element wastewater reached equilibrium within 3 hrs with MAC and CAC. The optimum pH of adsorption for MAC is at 5.83. The MAC outperform CAC in terms of having a higher adsorption capacity, qe and it has more effective in removal rate over a wider range of pH. It is also noted that the removal of Cd, Pb, As and Cr by MAC is significant. The present study provides prospective and effective adsorbent for multiple heavy metals removal in industrial wastewater
