摘 要: 基于氯气可以使酸性溴化钾 -甲基橙溶液褪色的反应 ,提出了一种使用动力学方法测量氯气含量的新方法 ;对该方法的定量原理进行了详细的理论分析 ,并通过一套简单的装置验证了这一原理 ;本文所描述的方法在保持推荐方法即甲基橙比色法优点的同时 ,大大缩短了测量时间 ,并使显色溶液的保存和使用更加方便。 A new kinetic spectrophotometry method to determine chlorine in atmosphere was described. The method based on the reaction between chlorine and acidic KBr-methyl orange solution. The principle of the method was discussed and confirmed with a simple setup. The method keep most of the advantage of the proposed method, methyl orange spectrophotometry, and is superior in determination time and treatment of the stock solution.
