【摘要】 <正> 为了建立操作简单装置的痕量金属的定量分析方法,近十年来人们提出了用摩尔吸光系数大的卟啉化合物作高灵敏显色剂的分光光度法。由于卟啉衍生物的灵敏度高及其与金属络合物的稳定性好,已引起人们的重视。由于工作的需要,最近我们合成了一个其有新型结构的卟啉衍生物TF_cooEtP,并对其与铜（II）反应的分光光度法进行了研究。目前报导的用于铜（II）测定的水溶性和非水溶性卟啉衍生物显色剂有TPPS₃、T（4-MPY）P、TPPS₄、T（3-MPY）P、T（4-CP）P、更多还原

【Abstract】 In this paper,α,β,γ,δ-tetrakis-[2-（3-carboxyethyl）furyl]porphine(TF_COOEP)was synthesized and its colour reaction with copper was studied.A coloured complex is formed in the presence of anionic surfactant,sodium benzenesulfonate and small amount of hydroxylamine.The complex formation is slow at room temperature,however,it can be accelerated by heating and was completed within 15 min at 100℃.The Soret band of the complex lies at 420 nm,which is well separated from that of the diacid form of TF_COOE?P（470 nm）.TF_COOE?P was found to be a highly sensitive and highly selective reagent for the direct spectrophotometric determination of ultramicro amount of copper.The molar absorptivity ε₄₂₀ is 1.52×10⁵ l·mol^-1·cm^-1.The interference of 19 ions and 6 salts was examined and found to be minimal.更多还原
