文摘This paper suggested a modified model of SLM which could improve its stability.In the model, an organic solution was sandwiched between two layers of supported film,which we called sandwich supported liquid membrane(SSLM).The transport experiments of La3+ were performed with SSLM containing HEH(EHP)as a carrier. The permeability coefficient (p) of La3+ were measured and some factors affecting the p were investigated. The results showed that if the pH of the feed was below 4.0,the p was increased with increasing in pH. The p was also increased when the strip acidity increases.Inspite of not enough satisfactory reproducibility on test result, the stability of the model was improved.
