摘要： 慈云祥等在研究铂、钯、金-碘化钾-丁基罗丹明B显色体系时发现,使用明胶或阿拉伯胶与TritonX-100的混合液,有良好的增溶作用和极好的增敏效应。我们的研究表明:在不少离子缔合物显色体系中,聚乙烯醇-TritonX-100或阿拉伯胶-β-环糊精等混合液,也有很好的增溶(或分散)、增敏和增稳作用。

Abstract: The effects of macromolecular compounds (polyvinyl alcohol (PVA), arabic gum)-Triton X-100 mixture on the coloured ion-associated complex systems are investigated. It is found that these mixtures have good solubilization actions on many coloured ion-association complexes. The mechanism of the effect may be the synergism of PVA(arabic gum) and TritonX-100 which changes the microenvironment of the colour system. It creates a steric environment that is both benificial to the formation of ion-association complex and the accumulation of more colour reagent molecules. The formation of the complicated ion-association complex carried non-stoichiometric additional reagent molecules results in an increase of sensitivity.
