摘　　要：本文评价了固体基质阴离子交换纤维素膜（ＤＥＡＥ膜）和微晶纤维素膜，且将此基质用于在重原子盐ＣｓＣｌ存在下，对氨基马尿酸的室温光法测定。重原子对ＲＴＰ有显著增强作用，且呈Ｃｓ￣＋＞＞Ｉ￣－＞Ｂｒ￣－＞Ｃｌ￣－的趋势。对有关的实验条件：烘烤温度、点样时机、介质ｐＨ、重原子浓度和ＲＴＰ稳定时间作了详细探讨。上述两种基质上，对氨基马尿酸的检出限和线性范围与滤纸上的结果相类似，特别是本文所得检出限均低于文献报道值。DEAE menbrane and Crystalline cellulose membraneas solid substrates have been evaluated and used to roomtemperature phosphorimetric determination of aminohip-puric acid. Heavy atom has significant enhancefnent effecton RTP signal with the trend Cs￣->>I￣->Br￣->Cl￣-.Related experimental conditions including drying tempera-ture, spotting time, solvent pH,concentration of heavyatom present and steady time have been described in de-tail.Limits of detection and linear dynamic range foraminohippuric acid on above substrates are found to be si-milar to that found using filter paper. Especially,limits ofdetection on paper are all lower than the values reportedin the literature.
