Abstract

Kaolin is a clay mineral composed of silica tetrahedral and octahedral alumina layers, which have high absorption capacity and are abundant in nature. This study aims at determining the optimum temperature of kaolin calcination and the effect of variations in pH, stirring time, kaolin mass, and stirring speed on the reduction of organic matter in peat water. The decrease in organic matter in peat water was measured using a UV-Vis spectrophotometer. The adsorption process was carried out by the batch method. The organic matter was calculated as the percentage decrease in absorbance at a wavelength of 254 nm. The optimum temperature for kaolin, which gives the best adsorption results, is obtained at a temperature of 400 ℃. The process of decreasing the optimum organic matter in peat water with pH = 4, stirring time of 1.5 h, kaolin mass of 500 mg/50 mL of peat water, and stirring speed of 150 rpm with a percentage decrease in organic matter content of 75.53%.
