摘　　要：4—甲氧基苄叉绕丹宁是一种能较简便测定银离子含量的显色剂,其检测限为,0.4～0.8μg/ml,摩尔吸光系数为1.10×10~4L·mol^(-1)·cm^(-1)。New reagent 4-Methoxybenzalrhodanine has been prepa prepared by reaction of 4-Methoxybenzaldehyde with Rhodanine. with this reagent a rapid, sensitive and selective spectrophothometric determination of siivev can successfully be carried out in an alkaline solution, It has an absorption maximum at 444nm and the apparent molar absorptivity is 1.10×10~4·L·mol^(-1)cm^(-1).
