Palm kernel shell charcoal (Elaeis guineensis Jacq.) has potential as a heavy metal adsorbent, but its adsorption efficiency is relatively low. To increase the adsorption capacity of palm kernel shell charcoal on an adsorbate such as metal ions, activation of palm kernel shell charcoal with NaOH is one of the efforts. Adsorption competition between Pb (II) and Cu (II) metal ion in the mixture is analyzed by means of palm kernel shell activated carbon. The method used in this research is batch adsorption by varying activator concentration (0.05; 0.1; 0.2 and 0.3 M), adsorbent dose (0.25; 0.5; 1.0; 1.5 and 2.0 g) and contact time (20; 40; 60 and 80 min). The characterization of palm kernel shell activated carbon refers to SNI 06-3730-1995 on iodine absorption test. Palm kernel shell activated carbon after activation was analyzed by SEM to determine the morphology. Pore size of palm kernel shell charcoal was analyzed using ImageJ software. Palm kernel shell charcoal before and after adsorption was analyzed by FTIR to determine the functional groups contained in palm kernel shell charcoal. Atomic absorption spectrophotometer (AAS) was used to analyze the residual content of lead (II) and copper (II) metal ions. The characterization results of the palm kernel shell activated charcoal showed the optimum activator concentration of 0,1 M and iodine adsorption capacity was 1230.18 mg/g with a pore size of 0.875 µm. The best adsorption conditions were obtained at 1 g biosorbent dose and 60 min contact time for lead(II) and copper(II) ions with 83.89% and 94.88% adsorption efficiency and 4.1244 mg/g and 4.6992 mg/g adsorption capacity, respectively. The adsorption kinetics model was pseudo-second for lead(II) and copper(II) ions with R2 of 0.9995 and 0.9996, respectively, with reaction rate constants of 0.5452 and 0.5571 g/mg min. The adsorption of lead(II) and copper(II) metal ions in mixed solution showed competition. Copper(II) metal ions are more competitive in terms of ion radius factor. However, lead(II) metal ions are more competitive when viewed from the covalent index value.
