“…Compared to other treatment systems, adsorption is an inexpensive, accessible and feasible method for the decontamination of water containing copper at very high concentrations. The effectiveness and simplicity of this method for copper removal has been proven by some researchers such as Maruf Mortula et al in the study of Copper Removal via Adsorption [18], Muhammad Shahrain Shuhaimen et al in the adsorption study of removal of copper ions from aqueous solution using modified sodium hydroxide: carica papaya peels [19], Victor Uzoma Nwagbara et al in evaluating the potential effectiveness of Moringa oleifera seed biomass as an adsorbent for copper removal from water [20] and P. Hanzlík et al in the adsorption of copper, cadmium and silver from aqueous solutions on natural carbon materials [21].…”

Copper is considered a heavy metal that can be toxic at certain concentrations and its presence in water is a potential threat to public health. These heavy metals also contribute to a remarkable degradation of the environment, hence the need for effective treatment methods to remove them. In this study, a mixture of titaniferous sand and calcium silicate was used as adsorbent material to eliminate copper in solution. The calcium silicate was synthesised from fluosilicic acid, which is a by-product of phosphoric acid manufacture. The titaniferous sand is a residue from a mining industry. Both adsorbents were characterised by infrared spectroscopy and X-ray fluorescence to determine their compositions and physicochemical properties. The response surfaces, through the Box-Behnken model, were used to model and optimise various adsorption parameters, namely initial copper concentration (A: 60 -200 mg/L), adsorbent dose (B: 0.1 -0.6 g) and pH (C: 4 -10). The copper removal efficiency (98.92%), after statistical analysis, was obtained under the following optimal conditions: an adsorbent dose of 0.55 g, an initial copper concentration of 197.25 mg/L and a pH of 9.85. The study of the effects of the operating parameters showed that they had a positive effect on the copper removal efficiency.
