摘要
A fluorescence quenching system of Cu 2+ Tb TMA Triton X 100 (TMA: benzene 1,3,5 tricarboxylic acid) was established for the determination of Cu 2+ . The fluorescence intensity of the determination system is linear in the concentration range of 1.58×10 -7 ～2.83×10 -5 mol·L -1 Cu 2+ . The proposed method was applied to the determination of Cu 2+ contained in various copper ores with satisfactory results.
