Establishment and validation of the water-rock intereaction modelling between the Malan loess and Cr(Ⅲ)

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 ...
