Determination of Trace Copper with Sulfophenylazo Rhodanine by Catalytic Dynamic Spectrofluorimetry

Abstract:

Series new methods were established which were based on the research of determination of trace copper with four sulfophenylazo rhodanine derivatives by catalytic dynamic spectrofluorimetry under the optimum conditions. This proposed method was applied to the determination of copper in real samples with satisfactory results. According to experiment results, the influences of different active groups and substitution positions on fluorescent property of rhodanine derivatives were investigated and the relationship between molecule structure and fluorescent property was explored.
