摘　　要：固相分光光度法是一种简单、快速、灵敏的新型痕量分析方法。本文首次提出用聚酰胺做固体吸附剂 ,采用激发光谱进行测定 ,克服了固相分光光度法背景大的缺点 ,同时能大幅度提高灵敏度 ,这种方法有良好的加标回收率、精密度及较高的准确度。并可将固相分光光度法的应用由仅能分析痕量的无机离子 ,推广到测定合成色素。Solid phase spectrophotometry is a mew,simple, fa st and sensitive trace analytical method.In this report,it is presented with a m ethod that the polyamide was used for the absorbence and the excitation spectra was measured directly.The background of the solid phase spectrophotometry was ov ercome,the sensitivity was increased in a big way.The method is good standard ad dition recovery and precision,high accuracy.Not only the trace inorganic ion can be analysed by the solid phase method,but also the artificial synthetic pigment ,the result was satisfied.
