Extraction Efficiency of Chromium (Ⅵ) in Loess with Chitosan Solution

Li Yunwen;Li Li;Northwest of China Railway Science Research Institute Co.,Ltd.;  
Heavy metal is a kind of important environmental pollutants,a large number of waste water,waste residue containing chromium free emissions lead to different degrees of pollution,water,soil and biological. Loess area is widely distributed in our country,in a typical western loess as the object of this research,through indoor soil column leaching experiment,irrigation water and tracer chromium concentration as control factor,study the distribution,migration and transform rule of chromium in soil lager and adsorption properties of loess on chrome. Due to the structure of chitosan contains a large number of NH2and-OH,chitosan,therefore,it is good for heavy metal ions adsorption. Discusses the adsorption time,chitosan concentration,p H,solid-liquid ratio,temperature on chitosan adsorption of Cr(Ⅵ) in the loess extraction effect.
