Abstract
The optimum reaction conditions of ClO_2-Fe Ⅱ -luminal chemiluminescence CL system were studied by flow injection technique in detail . A new method of CL for the determination of chlorine dioxide is proposed . The detection limit of the method is 4.0 μg/L ClO_2 and the linear range is 4.0~680 μg/L. The method is highly selective , simple , sensitive and has been applied to the determination of ClO_2 in tap water with satisfactory results .
