1) The equations for determining the composition of a metal complex using an anion exchange resin have been derived by considering the complex formation equilibria in both the resin phase and the solution phase.<BR>2) The method based on these equations was successfully applied to the investigation of mercury (II)-nitrate complex at various external nitrate concentrations by means of the sodium nitrate-sodium perchlorate mixed solution.<BR>3) Mercury (II) adsorbed from a sodium nitrate solution exists in the form of Hg(NO<SUB>3</SUB>)<SUB>3</SUB><SUP>－</SUP> at the external nitrate concentration of 0.5∼1 M, Hg(NO<SUB>3</SUB>)<SUB>4</SUB><SUP>2－</SUP> at 3∼5 M and a mixture of Hg(NO<SUB>3</SUB>)<SUB>3</SUB><SUP>－</SUP> and Hg(NO<SUB>3</SUB>)<SUB>4</SUB><SUP>2－</SUP> at the middle of these concentrations, though no anionic complex appears to be present in an ordinary nitrate solution.
