| Abstract: | The sorption percentages of organic contaminants from refuse percolate by Na -, Ca 2 -, Al 3 - and Cr 3 -saturated montmorillonite and their influencing factors are studied in this paper. The results show that the sorption capacities of montmorillonite saturated by trivalent cation for phenol and COD are relatively high, and increase in order of Na -, Ca 2 -, Al 3 - and Cr 3 -montmorillonite. Higher pH values are favorable. Under the experimental conditions, the sorption percentages of phenol and COD by Cr 3 -montmorillonite are up to 67.5% and 60.3%, respectively. The sorption capacities of the several kinds of montmorillonite for dimethylbenzene are low. Different adsorption effects of different montmorillonite can be attributed to H-bonding mechanism. |
