Abstract
The influence of soil properties on the adsorption of short-chain perfluorocaboxylates (PFCAs) onto soil was investigated. The results showed that the adsorption data could be well described by both Freundlich and Virial isotherms as their correlation coefficients ranged from 0.9651 to 0.9989 and from 0.8670 to 0.9985, respectively. The linear regressions between individual soil property and distribution coefficient were conducted for determination of the dominant soil properties affecting the adsorption of short-chain PFCAs onto soil. The results indicated that the content of protein, anion exchange capacity (AEC), iron oxides and clay were the dominant soil properties, while there were no effects of the content of total organic carbon (TOC), humic acid, fulvic acid, saccharide, cation exchange capacity, and specific surface area on the adsorption. The results of multiple linear regression analysis showed that the importance of soil properties on the adsorption of short-chain PFCAs was according to the following orders, AEC>protein>clay>iron oxides.
