摘要

By means of electronic and NMR (~11B, ~31P) spectroscopy the complexation in systems Ni~11-HEDP and Ni~11-B(OH)_3-HEDP (Cni=0.2M) at different ratios of components in a wide range of solution pH was studied. Content of homo- and heteronuclear complexes was determined, most probable ways of nickel and boron coordination with HEDP in complexes was proposed. The diagrams of the distribution of HEDP and boron between forms of complexes were constructed.
