| 摘 要： | 提出了一种测量空气中微量氯气的方法。用亚硫酸钠溶液吸收空气中的氯气，将氯气转化为氯离子，然后利用硫氰酸汞法进行吸光光度测定。最大吸收波长为460nm。氯离子浓度在0～1．6mg·L-1范围内与吸光度值（△A）呈线性关系。本方法用于直接测定空气样品中的氟气，获得了满意的结果，方便、快捷。

| Abstract: | A simple and sensitive method for determination of micro chlorine in air has been developed. The determination is based on the reaction of sodium sulphite reducing chlorine to chlorion and the absorptiometric analysis with mercuric thiocyanate method. The linear range of chlorion concentration with△A is 0- 1.6 mg · L-1. The method has been used conveniently and rapidly for determination of micro chlorine in air samples with satisfactory results. |
