简要介绍了使用检测管测定空气中氯的方法。检测管含有固定试剂4-氨基安替比林和N-(1-萘基)乙二胺二盐酸盐的硅胶,这些试剂通过亚硫酸钠和三甘醇稳定。 15 至 150 mg m - 3 范围内的氯浓度是根据指示剂层的蓝紫色着色的长度来评估的。
Brief information is given on a method of determination of chlorine in air using a detector tube. The detector tube contains silica gel with immobilized reagents 4-aminoantipyrine andN-(l-naphtyl)ethylenediamine dihydrochloride which are stabilized by sodium sulfite and triethylene glycol. Chlorine concentration in the range 15 to 150 mg m - 3 is evaluated on the basis of the length of the blue-violet coloration of the indicator layer.
