摘要：

The paper presents the results of studies on the extraction of nickel(II) and cobalt(II) ions from sulphate solutions with di(2-ethylbexyl)phosphoric acid (D2EBPA). As the modifier of extracting capacity, tributyl phosphate (TBP) was used. The obtained experimental results indicate that a high excess of TBP in relation to D2EBPA reduces the extracting capacity of the latter, whereas its small amount (in a proportion of 1:1) improves the extraction of nickel(M ions, while not affecting the extraction of cobalt(II) ions.
