丙酮化学发光反应中卤素离子敏化效应的研究

STUDY OF THE HALIDE SENSITIZATION EFFECT IN ACETONE CHEMILUMINESCENCE REACTION

本文报导了丙酮化学发光反应中卤素离子的敏化效应,对其敏化机理进行了探讨,并研究卤素离子敏化效应的分析应用。

In basic medium, acetone can react with CIO- and H2O2 to produce chemiluminescence (CL) emission. The halide ions were found to sensitize the acetone CL reaction. The mechanism of the halide sensitization effect has been briefly discussed. Based on this effect, a novel CL method for the determination of iodide ion was proposed. The experimental results illustrate that the detection limit is 2.0×10-11g/ml I-, and the linear range is 4.0× l0-1g/ml to 3.0×10-7g/ml. The effect of some foreign ions was also studied.
