摘　　要：在氨水介质中 ,痕量对乙氧基苯胺能灵敏地阻抑 Cu2 +催化过氧化氢氧化茜素红的褪色反应。本文研究了该反应的动力学参数 ,建立了一种测定对乙氧基苯胺的新方法。该法测定对乙氧基苯胺的线性范围为 0 .0～ 1 .0 μg/ 2 5m L,检出限为 8.54×1 0 - 7g/ L。用于环境水样中对乙氧基苯胺的测定 。It has been observed that p ethoxyaniline can sensitively inhibit the reaction of H 2O 2 oxidizing discoloration of alizarian red catalyzed by Cu 2+ in NH 3·H 2O solution. The kinetics of the reaction was investigated. A new method for the determination of p ethoxyaniline was proposed. The detection limit was 8.54×10 -7 mol/L and the calibration graph was rectilinear in the range of 0.0~ 40.0 μg/L for p ethoxyaniline. It has been applied satisfactorily to the determination of p ehtoxyaniline in waste water.
