Optimasi Konsentrasi Aktivator Dan Ph Adsorben Arang Kulit Durian (Durio Zibethinus Murr.) Teraktivasi Naoh Dalam Penjerapan Kromium (III)

---

Durian peel contains high levels of cellulose, namely around 50-60%. This shows that durian peel is not just a waste, but it can produce activated carbon. This research aims to identify the effect of activators on the characteristics of durian peel carbon and determine the optimum pH for the adsorption activated carbon from durian peel on chromium (III) metal. Durian peel was converted into carbon by carbonization process at 320 ℃ for 1 hour. Durian peel carbon was then activated using NaOH with a variation of 0.1; 0.2; 0.3; and 0.4 M. Durian peel activated carbon was characterized based on SNI No. 06-3730-1995 to determine the optimum activator concentration. Determination of pHpzc was carried out to determine the surface charge of the adsorbent. The adsorption method used in this research was batch adsorption of chromium (III) metal with pH variations of 2, 4, 6, and 8. Analysis of the surface morphology of the adsorbent was carried out using SEM-EDS. The functional groups of activated carbon from durian peel were analyzed using FTIR. Optimum conditions were obtained at an activator concentration of 0.3 M with a water content value of 4.65±0.56%; ash content 4.65±0.56%; iodiume adsorption capacity 797.24±6.82 mg/g; methylene blue adsorption capacity 24.88±0.00 mg/g; and surface area 92.26±0.01 m2/g. The pHpzc of durian peel charcoal at a concentration of 0.3 M was 5.83. The optimum pH was obtained at pH 6 with an efficiency of 98.71% and a capacity of 2.91 mg/g. The pore size carbon from durian peel before activation is 1.326 µm, while after activation it is 1.825 µm. The adsorption results were also proven by FTIR analysis, there was an O-Cr functional group at a wave number of 835.01 cm-1. Based on the research, it can be concluded that activated carbon from durian peel was effective in adsorbing chromium (III) metal and the activator concentration and pH parameters greatly influence the adsorption efficiency and capacity.
