【摘要】 本文研究了镓（Ga）——茜素络合腙（ALC）——溴化十六烷基吡啶（CPB）三元络合物的生成.实验发现溶液的pH、ALC和CPB之间存在着明显的交互作用.我们应用改进的单纯形确定了最优反应条件.在该条件下,摩尔吸光度(λ_510nm为1.5×10⁴ι·mol^-1·cm^-1,它比经典方法确定的条件,灵敏度提高了两倍.反应的选择性也较好.更多还原

【Abstract】 This paper deals with the ternary complex formation of gallium（Ga）alizarin complexone（ALC）-cetylpyridinium bromide（CPB）.Interactions among the pH,ALC and CPB have been found to exist by our experiments.A Modified Simplex method has been used to obtain the optimal condition of the reaction.Under this condition,the molar absorptivity is found to be 1.5×10⁴ l·mol^-1·cm^-1at λ_510nm.Compared with the classical approach,the sensitivity of the reaction in this method has increased by twice and the selectivity has got better.更多还原
