Degradasi Senyawa Organik pada Palm Oil Mill Secondary Effluent Menggunakan Fotokatalis TiO2

Abstract

Degradation of organic compound on palm oil mill secondary effluent by photocatalytic process using TiO₂ photocatalysts with aeration of air has been carried out in the semi batch photo-reactor system equipped with mercury 350 W lamps. The concentration of organic compounds in POMSE was analyzed by UV-Vis Spectrophotometer. Photodegradation performance test showed that TiO₂ photocatalyst was able to degrade organic compounds and could eliminate phenol pollutans in POMSE effectively, where the degradation performance of organic compound from TiO₂ photocatalyst was respectively 31.36% and phenol elimination up to 96.66% (loading TiO₂ = 1.5 g/L, air flow rate = 10 cc/min) at minutes-120. The result also showed that the performance of TiO₂ photocatalyst in degrading organic compound was stable at 25.25 to 31.36% for two hours (COD POMSE of 250 to 650 ppm).
