Abstract
To evaluate the effects of dissolved organic carbon on sorption of 3,4-dichloroaniline (3,4-DCA) and 4-bromoaniline (4-BA) on soils, batch sorption experiments were carried out. The soil used was a typical calcareous soil from south-eastern Spain. Two different types of dissolved organic carbon were used, that is, dissolved organic carbon extracts from a commercial peat (DOC-PE) and high-purity tannic acid (DOC-TA). The experiments were carried out in a 0.01 M CaCl2 aqueous medium at 25 °C. The results obtained from the sorption experiments show that the presence of both DOC-PE and DOC-TA, over a concentration range of 15-100 mg lâ1, produced in all cases, an increase in the amount of 3,4-DCA and 4-BA adsorbed on the soil studied.
