Pemanfaatan Arang Aktif Dari Limbah Kulit Durian (Durio Zibethinus Murr.) Sebagai Biosorben Logam Kadmium (II)

---

Durian peel (Durio zibethinus Murr.) has the potential to be used as a biosorbent in the form of activated charcoal because it contains 50-60% cellulose and its adsorption capacity can be increased by activation. The activation carried out in this study used NaOH with varying activator concentrations (0.1; 0.2; 0.3 and 0.4 M) so that it is hoped that the optimum activator concentration can expand the porosity and increase the surface active groups of durian skin activated charcoal. This research aims to determine the efficiency and adsorption capacity of durian peel activated charcoal against cadmium (II) metal. The method used in this research is adsorption on NaOH-activated durian peel activated charcoal against cadmium (II) metal with pH variations (2, 4, 6 and 8). Biosorbents are characterized according to SNI No. 06-3730-1995 with an optimum activator concentration of 0.3 M including water content of 4.65%, ash content of 4.65%, adsorption capacity for iodine of
797.24 mg/g and adsorption capacity for methylene blue of 24.884 mg/g. The morphology of the biosorbent surface was analyzed using SEM and the elemental composition of the biosorbent surface was analyzed using EDS containing the elements carbon (C), oxygen (O), magnesium (Mg) and potassium (K), and the pore size of the biosorbent was analyzed using ImageJ software with the results before activation it was 1.326 μm and after activation it was 1.931 μm. The functional groups in the biosorbent were analyzed using FTIR, including the N-H, O-H, C-H, C=O, C-C and O-Cd groups. The results after adsorption of cadmium (II) metal were analyzed using ICP-OES. Optimum adsorption parameters were obtained at pH 6 with an efficiency of 98.81% and a capacity of 2.9479 mg/g. Based on the research that has been carried out, it can be concluded that durian peel activated charcoal biosorbent has high effectiveness in adsorbing cadmium (II) metal at pH variations.
