摘要: 目前在用水溶性卟啉衍生物作显色剂方面已有文献总结[1]。但对非水溶性卟啉则研究得较少。就测定痕量铅而言,皆用水溶性卟啉衍生物,而用非水溶性卟啉测定铅,则尚未见报导[2-6]。
Abstract: The water-insoluble porphine,meso-tetrakis-(4-acetyloxylphenyl)porphine(T(4-AOP)P),has been synthesized and its colour reaction with lead(Ⅱ)has been studied.The lead(Ⅱ)complex was formed in the presence of sodium dode-cyl sulfate.The complex formation was slow at room temperature,however,it could be accelerated by heating at 100℃ for 12 min.The soret band of the complex lies at 466nm,which is well separated from that7 of the reagent(420nm)at pH9.5.Apparent molar absorptivity of the complex is 2.6×105 lmol-1 cm-1.Beer's law is obeyed in the rang of 0-6μg/10ml for lead(Ⅱ).Tolerance limits were shown for 24 ions.The method established could be applied to the ditect determination of lead(Ⅱ)in sodium chloride with satisfactory result.
