Adsorption Characteristics of Cd2+on Combined Modified Xinjiang Gray Desert Soil with BS-12 and SDS
BS and SDS were selected to modify the grey desert soil in Xinjiang according to different proportions,and eight kinds of modified soil samples were prepared.The adsorption performance of Cd2+ was tested under the same conditions with the original unmodified soil sample(CK)as the control,and the adsorption characteristics of Cd2+ in the grey desert soil were described through the Langmuir isotherm adsorption model,The results indicate that the modification of Xinjiang gray desert soil with a combination of amphoteric anionic surfactant system can significantly improve its adsorption performance for Cd2+.
