Abstract

Adsorption using biosorbent become an alternatif for recovery heavy metals such as gold from electronic waste. Mangosteen rind can adsorp Au(III) ions in acid condition pH 2 optimally. Kinetics study of Au(III) ions adsorption using mangosteen rind was aim to determine adsorption kinetics model, adsorption rate constanta (k) and activation energy (Ea) Au(III) ions using mangosteen rind. Adsorbent. Adsorbent preparation was carried out using maceration methof for activate adsorption functional group and remove contaminant materials. Au(III) ions adsorption was analyzed by varying temperature and time. Adsorbed Au(III) was determined using Atomic Adsorption Spectroscopy (AAS) and characterized using Fourier Transform Infra Red (FTIR) Spectroscopy dan X-Ray Diffraction (XRD) Spectroscopy. The result proved that KBM adsorbent could adsorp Au(III) ions effectivelly and follow Ho pseudo-second order kinetic with Ea of 24,65 kJ/mol and k of 2.05x10-3 ( 40℃); 3.63x10-3 ( 50℃) dan 3.60x10-3 ( 60℃) g mg-1 minutet-1 respectivelly.

Abstract

Although Palm Oil Mill Effluent (POME) can be used as a raw material for biodiesel production, the POME contains an excessive amount of Free Fatty Acids (FFA), necessitating a preliminary process and esterification. POME is degummed using phosphate acid and bleached with carbon active. Additionally, this study used KOH-impregnated zeolite to reduce FFA. The purpose of this study is to determine the effect of adding impregnated zeolite on esterification. POME was heated to 600C for 30 minutes, then degumming with 3 % of phosphate acid for 30 minutes, followed by bleaching with carbon active with a comparison ratio of 8:3 at 1000C for 1 hour, and finally, esterification with 3 percent impregnated zeolite from the POME weight at 600C for 4 hours. The analysis was conducted using titration methods to determine the FFA of each esterification. The data will be compared between zeolite and non-zeolite degumming, bleaching, and esterification. The results indicated that the most effective method for reducing FFA was degumming, bleaching, and esterification with zeolite.
