摘　　要：随着高新技术的迅猛发展,对银的测试灵敏度要求越来越高。针对吸光光度法测定银的200多种显色反应体系进行了分类、筛选,找出了60多种高灵敏显色体系[ε>105L/(mol.cm)],为进一步探索新的显色试剂和显色体系提供参考。The dramatic developments of modem high-and-new technologies require more and more sensitive methods for the silver determination. This paper classified and sifted about 200 chromogenic systems which have been used for the silver determination by photometry, and found out more than 60 highly sensitive chromogenic systems ε 〉 10^5 L/（ mol ·cm） among them. It will be helpful for searching new chromogenic reagents and new chromogenic systems, and also helpful for further exploration on this field.
