UV-vis and fluorescence spectra for interaction silver(I) ion with tryptophan (Trp) have been studied. The influence of pH of media, multicomponent concentration, including amino acids, silver(I) ion, formaldehyde, sodium dodecyl sulfate (SDS), and trihydroxymethylaminomethane (Tris) as well as temperature, illumination, time, etc. on reaction were investigated, and the mechanism of reaction has been explored. The results shown that the optimum condition for the interaction between tryptophan and silver(I) ion were found.
研究了银（I）离子与色氨酸（Trp）相互作用的紫外可见光谱和荧光光谱。考察了介质pH值、包括氨基酸、银（I）离子、甲醛、十二烷基硫酸钠（SDS）和三羟甲基氨基甲烷（Tris）在内的多组分浓度以及温度、光照、时间等对反应的影响，并探讨了反应机理。结果表明，找到了色氨酸与银（I）离子相互作用的最佳条件。
