title: Interaction of nitrosylruthenium with glycine and alanine in seawater--studies on nitrosylruthenium complex-formations with glycine and alanine by a chelating resin.
abstract: RuNO-Chelex 100 resin, [R.RuNO(OH)(OH2)] was prepared by the reaction of RuNO-chloro complex with Chelex 100 resin, and it is expected that aqua and hydroxo groups contained in RuNO-Chelex 100 resin act as adsorption sites for glycinate or alaninate anion by ligand-exchange reaction. The equilibrium constants, Keq, of 1:1 complex formation reactions of RuNO-Chelex 100 resin with glycine and alanine were found to be 96.3 +/- 5.76 and 82.6 +/- 2.69, respectively. The inhibitive effect of glycine and alanine on adsorption of [RuO2(NO2)-(NO3)(H2O)NO]- to anion exchange resin increased in the order of glycine greater than alanine. It was observed that the inhibitive effect was dominated by Keq of RuNO-Chelex 100 resin with glycine and alanine.
