Extraction equilibria in the zinc nitrate-water-methyl diphenyl phosphate (MePh2PO4) and copper nitrate-water-MePh2PO4 systems have been investigated. The data found are consistent with formation of partially dissociated [Zn(NO3)2(H2O)2(MePh 2PO4)3] and [Cu(NO3)2(H2O)3(MePh 2PO4)3] complexes. In the case of zinc, the equilibrium constant for complex formation K = (3.6 ± 0.7) × 10-6 (mol kg-1 MePh2PO4)-1.
