摘要
以硫酸为介质,用适宜的氧化剂氧化卤化物生成卤单质(X2),用载气载出,被显色剂(CD-4)吸收,生成一种有色化合物,在510nm处测其吸光度.并对实际水样进行了分析.
The halide can be oxidized with a suitable oxidizing agent to produce halogen gas that can be absorbed by CD4 to form a colored compound. The absorbance of the compound can be measured at 510 nm and therefore the halide can be determined. The method has been used to determine trace chloride in tap water.
