Abstrakt: The study to reduce heavy metals pollution from water using the KOH-activated carbon was studied the factors affecting the adsorption capacities of Cu (II) and Pb (II), in particular, initial metals concentration, pH of the solution, and contact time in static conditions. Using X-ray photoelectron spectroscopy and FTIR analysis to determine the elemental composition and surface functional groups of the activated carbon surface, the presence of oxygen-related functional groups was observed. The maximum adsorption capacities were 135.8 mg/g and 31.0 mg/g for removal of lead and copper solutions with the initial concentration of 300 mg/L of metal at 318 K, respectively. The removal percentage was found to be higher for Pb (II) when compared with Cu (II). [ABSTRACT FROM AUTHOR]
