摘要
利用红外光谱和紫外光谱研究了化学法二氧化氯发生器所产生的二氧化氯混合消毒液的光谱性质．氯酸钠和盐酸反应体系温度的升高，有利于二氧化氯纯度的提高；混合气体通过尿素溶液进行纯化，可大大提高二氧化氯的纯度．
The UV and IR Spectra of mixture of chlorine dioxide and chlorine, produced from chemical chlorine dioxide generator, were measured. It is favorable to raise the purity of ClO 2 by the reaction of sodium chlorate with hydrochloric acid if the reaction temperature was elevated. The purity of ClO 2 was also raised greatly by purification of urea.
