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.
RuNO-螯合树脂100([R.RuNO(OH)(OH₂)])通过RuNO-氯配合物与螯合树脂100反应制备,预计RuNO-螯合树脂100中含有的水合基团和羟基基团通过配体交换反应作为甘氨酸根或丙氨酸根阴离子的吸附位点。发现RuNO-螯合树脂100与甘氨酸和丙氨酸形成1:1配合物反应的平衡常数Keq分别为96.3±5.76和82.6±2.69。甘氨酸和丙氨酸对[RuO₂(NO₂)-(NO₃)(H₂O)NO]-吸附到阴离子交换树脂上的抑制作用按甘氨酸大于丙氨酸的顺序增加。观察到抑制作用主要由RuNO-螯合树脂100与甘氨酸和丙氨酸的Keq决定。
