The objective of this study was to characterize the parameter conditions such as optimum weight, contact time, pH, and concentration of the copper solution upon the absorption of biocharcoal derived from nutmeg shell. The concentration of copper ions was measured at a wavelength of 324.7 nm using an atomic absorption spectrophotometer (AAS). Results showed that the optimum adsorption of Cu(II) ions on the optimum weight of biocharcoal was 125 mg, the percentage of Cu(II) ions adsorption was 95.69%, and the weight of Cu(II) ions adsorbed was 11.48 mg/g. The optimum contact time was obtained at 60 minutes with the adsorption percentage of Cu(II) ions of 98.19%, in which the weight of adsorbed ions was 10.25 mg/g. The optimum pH was obtained at pH 7.0 with the adsorption percentage of Cu(II) ions was 99.95%, with the weight of adsorbed Cu(II) ions was 11.99 mg/g. The optimum concentration was obtained at 20 ppm with the adsorption percentage of Cu(II) ions was 99.75%, whereas the weight of the adsorbed Cu(II) ions was 7.99 mg/g. The maximum adsorption capacity of biocharcoal against Cu(II) ions using the Langmuir isotherm equation was 62.50 mg/g biocharcoal.
