研究了Ａｇ（Ｉ）与ｍｅｓｏ－四（对－磺酸基苯基）叶琳的光催化显色反应。在ｐＨｌ０的缓冲溶液中形成稳定的Ａｇ（Ｉ）－ＴＰＰＳ＿４－ＣＴＭＡＢ三元配合物，其最大吸收波长为４２６ｎｍ，组成为Ａｇ（１）ＴＰＰＳ＿４：ＣＴＭＡＢ＝１：１：２。表观摩尔吸光系数为２．７９×ｌ０￣５Ｌ·ｍｏｌ￣－１·ｃｍ￣－１，Ａｇ（１）的浓度在０～０．２μｇ／ｍｌ内符合比尔定律。基于此建立的测Ａｇ（Ｉ）方法灵敏度高，结合巯基棉分离干扰，可用于矿物中Ａｇ（Ｉ）的测定。
The photocatalytic color reaction of Ag (I) with meso-tetrakis (p-sulfonatophenyl) ylene was studied. The stable Ag (I) -TPPS_4-CTMAB ternary complex was formed in buffer solution of pH10 with the maximum absorption wavelength of 426nm and the composition of Ag (1) TPPS_4: CTMAB = 1: 1: 2. Apparent molar absorption coefficient of 2.79 × l0 ~ 5L · mol ~ -1 · cm ~ -1, Ag (1) in the concentration of 0 ~ 0.2μg / ml within the Beer’s law. The Ag (I) method established based on this method has high sensitivity and can be used for the determination of Ag (I) in minerals by combining the separation and interference of sulfhydryl cotton.
