臭氧是强氧化剂，用作氯（饮用水消毒中的生物灭杀剂）的替代品。臭氧能用作去除异味，脱色，并且能控制海藻和其他水生生物的生长。DDPD方法参考：CHEMetrics开发DDPD是DPD试剂的甲基替代产物。在分析之前要在样品中加入A-7400活化剂溶液（碘化钾）。臭氧同碘化物反应产生碘。然后碘同试剂反应产生一种紫色物质。多种游离的卤素和卤化剂能在试剂中显色。样品中如果含有低于25ppm的铬酸盐将不会影响测量结果。测量结果用ppmO3表示。靛蓝法参考：Rader H.，J. Hoigen，“靛蓝法测量水中的臭氧”，水研究，第15卷，第449-456页，1981；APHA标准方法，第21版，方法4500-O3 B（2005）使用靛蓝法时，靛蓝色的三磺酸盐马上同臭氧反应，与存在的臭氧的数量成比例地定量漂白蓝色。在试剂中含有丙二酸以防止3ppm以下的氯的干扰。测量结果用ppm O3表示。美国CHEMetrics中国代理商：上海益朗仪器有限公司 http://www.shylyq.com
