| Abstract: | The membranes of polyvinylidene fluoride are used to study the transfer and extraction performances of Sm() and Nd() with the extraction system of HEH/EHPkerosene.The results show that the extraction reaction could be thought as quasifirst order reaction whether the extractant is ammoniated or not.The effect of HEH/EHP ammoniated on membrane resistance and the exchange relationship of Ln3 ,H and NH 4 are discussed in extraction and extractionstripping processes. |
