Abstract

Arsenic adsorption on soils plays an important role in controlling mobility, bioavailability and toxicity of arsenic in the environment. Kinetic studies on arsenic adsorption are often done at soil to water ratios of 1:10 to 1:50, which generally make the conditions of the study different from the prevailing field situations. In this study, kinetics of arsenic adsorption were investigated in five arsenic-uncontaminated agricultural soils at saturation moisture content of 50% over long periods of time (2 minutes to 20 days). Six kinetic models were fitted to the data. The kinetics of arsenic adsorption on soils were nonlinear and biphasic. Arsenic adsorption rates were initially rapid, but gradually decreased with time and reached a plateau after 72 hours. The cumulative amount of arsenic adsorbed by soils ranged from 158 to 210 mg/kg, 47-67% of it was adsorbed in the first two minutes (the first measurement time) and 68-86% of it was adsorbed in the first hour of the reaction. Cumulative adsorption of arsenic on different soils was reduced by 1.9-16% in the presence of 100 mM phosphate, 0.7-9% in the presence of 100 mM citrate and 0.6-9% in the presence of 10 mM phosphate as compared to arsenic adsorption alone. The simplified Elovich model with the higher coefficients of determination ( ) values (0.93-0.96) and lower standard errors of the estimate values (5.1-6.5 mg/kg) best described arsenic adsorption data in all soils compared to zero-, first-, and second-order, power function and parabolic diffusion models.
