摘要
Abstract
The results of column experiment and batch experiment show that the removal rate of Cr( Ⅲ ) by the Malan loess could reach 95％. The surface characteristics of the Malan loess such as physico-chemical properties, surface structure, concentration of surface site, cation exchange capacity were analyzed with some advanced equipments, for example, SEM, EDS, IR, XRD, etc and the water-rock interaction modeling between the Malan loess and Cr ( Ⅲ ) was built. The different initial concentration experiment, non-calcites Malan loess experiment and the formation extraction experiment were designed. By comparing analyses of the simulating results and the experimental results, the reliability of the model was validated. The results show that the model precision was 90％ when the concentration of solutions ranged from 1 to 100 mg/L, which give a good description of the reaction process. The result enriches the mechanism of water-rock interaction modeling between the Malan loess and Cr ( Ⅲ ).关键词
