Abstract

When a hydrophobic compound goes in to the soil, it is likely to be absorbed. Sorption does not result in the toxic reduction but it reduced the degradation rate due to the decreased bioavailability. In this article, laboratory experiments were designed to acsess the sorption characteristics of hydrophobic compound (dibenzofuran) in three soils with different physicochemical characteristics, also evaluate the role of soil organic matter toward sorption. Soil samples, Grumosol and Latosol were taken from Gunung Kidul, Yogyakarta and Andosol from Sragen, Central Java. Dibenzofuran sorption isotherms on soil were obtain by the batch aqueous system with initial dibenzofuran solutions 4, 12, 20, and 28 mg.L-1. The system were shaken for 24 h. The concentration of dibenzofuran in the liquid phase was determined using GC after extracted using ethyl acetate and dried by Na2SO4. Sorption-desorption isotherms were fitted to the Freundlich equation: S = Ks.CN. The results shows that Grumosol, Latosol, and Andosol has different characteristics at absorbing dibenzofuran. Grumosol has the highest affinity whereas the highest capacity belongs to Andosol. Different from Andosol and Latosol, the sorption capacity of Grumosol is affected by the concentration of soil organic matter.
