摘要
为快速、准确地测定出现场舰船火灾烟气中氯的含量,在体系中加入适量的十二烷基苯磺酸钠(DBS)、聚乙烯醇溶液(PVA)和吐温-80,对传统AgCl浊度法进行了改进。结果表明,系统的稳定性、灵敏度均大幅度提高,检测限则由3.5×10-1mg/l降低至3.1×10-2mg/l。改进后的方法线性范围宽、重现性好。
In order to determine the contents of chlorine in the fume of warships on fire, the method of AgCl turbidity is improved by adding appropriate dispersing agent and surface active agent such as sodium dodecyl benzene sulphonate （DBS）, poly（vinyl alcohol） （PVA） and twein- 80. The results show that the stability and sensitivity of the system are improved, and the detection limit is decreased from 3.5×10^-1mg/l to 3.1×10^-2mg/l. The improved method has wide linear range and high reproducibility.
