Abstract
The solvent extraction behaviour of Cu(II), with 4-alkyldithiocarboxylate derivatives of pyrazol (HDTC ; alkyl = benzyl, allyl, n-hexadecyl , n-octadecyl) was studied as a function of pH. Cu(II) is efficiently extracted ( > or = 80% ) in the pH range studied. In all cases the extracted specie was found to be Cu(DTC)2
