Palm kernel shells (Elaeis Guineensis Jacq.) are one of the palm oil wastes that have benefits, such as activated carbon for the adsorption of heavy metals. The cellulose contained in palm kernel shells plays an important role in carbon source the adsorption of heavy metals, the effectiveness of which can be increased through the activation process. Activation in this research using a base activator, namely NaOH, so it is hoped that more active sites will be available and expand the surface area for metal adsorption. This research aims to determine the competitive adsorption of Cadmium(II) and Iron(III) metals in mixed solutions using palm kernel sheels as activated carbon. The method that used in this research was batch adsorption method with varying activator concentrations (0.05; 0.1; 0.2 and 0.3 M), varying
adsorbent doses (0.25; 0.5; 1.0; 1.5 and 2.0 g) and varying contact time (60; 90; 120 and 150 minutes). The surface morphology of the palm kernel shell biosorbent was analyzed using SEM, the pore size of the biosorbent was determined using ImageJ software and the functional groups in the biosorbent were analyzed using an FTIR instrument. The SNI No.06-3730-1995 characterization carried out was the iodiume adsorption capacity test. The absorbance of Cadmium(II) and Iron(III) metals before and after adsorption was analyzed using an AAS instrument. The kinetic model is deterined based on pseudo first-order and pseudo second-order kinetic models. SEM and ImageJ results show that the optimum activator concentration is
0.1 M with a pore size of 875 nm. The research results showed the best adsorbent dose was 1.0 g and the best contact time was 120 minutes with adsorption efficiency and adsorption capacity on Cd2+ of 86.48% and 4.2626 mg/g while on the Fe3+ it was 88.64% and 4.3611 mg/g. The adsorption kinetics model follows pseudo second-order kinetics with a value of R2= 0.9978 for cadmium metal with a reaction rate constant of 0.1571 g/mg min-1 while for iron metal the value of R2= 0.9991 with a reaction rate constant of 0.1231 g/mg min-1. Based on the research, the concluded that palm kernel shells activated charcoal has higher adsorption effectiveness for Fe3+ metal ions than Cd2+ metal ions. Hence, iron metal is more competitive than cadmium metal.
