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_(cooEt)P,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TPPS_3、T(4-MPY)P、TPPS_4、T(3-MPY)P、T(4-CP)P、
In order to establish a method for the quantitative analysis of trace metals in simple devices, spectrophotometry using porphyrin compounds with high molar extinction coefficients as highly sensitive developers has been proposed in the past decade. Due to the high sensitivity of porphyrin derivatives and their stability with metal complexes, has attracted people’s attention. Due to the needs of the work, we recently synthesized a new structure of the porphyrin derivative TF_ (cooEt) P, and its reaction with copper (II) spectrophotometry were studied. The currently reported water-soluble and water-insoluble porphyrin derivatives for copper (II) determination are TPPS_3, T (4-MPY) P, TPPS_4, T (3-MPY) P, T ) P,
