摘要：

Bis(l,l,3,3-tetramethylbutyl)phosphinic acid (HMBP) as an extractant is of selectivity to many kinds of metal ions.1Bis(1,1,3,3-tetramethylbu1yl)dithiophosphinic acid (HDTP), which has a similar structure to HMBP, is stronger acid than HMBP; moreover, its extractive behavior is very different from HMBP to some metal ions as a result of S atom replacing of O in HMBP.2In order to understand its extraction mechanism and regularity, we selected metal ions such as ZnⅡ and CdⅡ for preparing extracted complexes and analyzing their structure. The composition of the complexes, M(DTP)2 (M=Zn, Cd), were supposed by elementary analysis, and confirmed by FT-IR and 1HNMR spectra.
