摘要
本文研究了三种邻菲罗啉类试剂对银（１）与六种不同取代基卟啉试剂显色反应的影响。研究结果表明：于ｐＨ９．２时在３５～４０℃放置１０～１５ｍｉｎ，银与邻菲罗啉类试剂和卟啉试剂能形成多元络合物。我们分别测定了Ａｇ－ｐｈｅｎ－ＴＰＰＳ＿４、Ａｇ－ｐｈｅｎ－Ｔ（４－ＭＯＰ）ＰＳ＿４和Ａｇ－ｐｈｅｎ－Ｔ（４－ＨＰ）ＰＳ＿４体系的络合比及稳定常数，详细讨论了Ａｇ－ｐｈｅｎ－Ｔ（４－ＭＯＰ）ＰＳ＿４体系的光度性质，把所确立的方法用于阳极泥、矽碳银中痕量银的测定，结果与ＡＡＳ很一致。
he photometric characteristics of silver with sixkinds of water-soluble porphyrines in the presence of1,10-phenanthrolines have been investigated.The ex-periments show that silver can form multicomponentcomplex with porphyrine and 1,10-phenanthrolineswithn15 min at 35～40℃ and pH9.2. The stahlityconstants and complex ratio of these complexes weredetermined respectively. The optimun conditions ofthe color reaction of Ag(I) with T(4-MOP)PS_4 and1,10-phenanthroline have been established.Thismethod can be used for the determination of mi-croamount of silver in anode mud and argysical withthe same results as determined by AAS.
