In this paper, the existing patterns of carbonate and ClO2 in the so-called "stabilized chlorine dioxide" solution which is stabilized by stabilizers Na2CO3 and H2O2 are analyzed. Meanwhile, thermostability, UV absorption spectrum, specificity of the paper chromatogram, microstructure and ionic chromatogram of this solution were studied, and contrasted with pure NaClO2 and ClO2. The results show that ClO2 in "stabilized chlorine dioxide" solution exists in the form of chlorite ClO2-, carbonate exists in the form of bicarbonate. Therefore, it is considered that "stabilized chlorine dioxide" solution is mixed solution of ClO2- and HCO3-, its pH being 8.5.
本文分析了由稳定剂碳酸钠和过氧化氢稳定的所谓“稳定二氧化氯”溶液中碳酸盐和二氧化氯的存在形态。同时,研究了该溶液的热稳定性、紫外吸收光谱、纸色谱特异性、微观结构和离子色谱,并与纯亚氯酸钠和二氧化氯进行了对比。结果表明,“稳定二氧化氯”溶液中的二氧化氯以亚氯酸根ClO₂⁻的形式存在,碳酸盐以碳酸氢根的形式存在。因此,认为“稳定二氧化氯”溶液是ClO₂⁻和HCO₃⁻的混合溶液,其pH值为8.5。
