摘要: 本文对以稳定剂H2O2和Na2CO3与ClO2制备的所谓“稳定性二氧化氯” 溶液中ClO2存在型体及碳酸盐存在型体进行了分析,同时对“稳定性二氧化氯”的热稳定性、酸活化影响因素以及杀菌效果等方面进行了研究,并与纯NaClO2和ClO2进行了对比.结果表明:“稳定性二氧化氯”溶液中ClO2是以亚氯酸盐ClO2-型体存在,碳酸盐是以碳酸氢盐型体存在.又通过理论分析证明“稳定性二氧化氯”溶液制备过程中ClO2与H2O2和Na2CO3发生了氧化还原和质子传递反应,生成了亚氯酸盐ClO2-和碳酸氢盐HCO3-,并有O2放出.因此,认为“稳定性二氧比氯”溶液是ClO2与H2O2和Na2CO3反应生成的ClO2-和HCO3-的混合溶液.Abstract: In this paper, the existential pattern of chlorine dioxide and carbonate in the "stabilized chlorine dioxide" solution prepared with H2O2, Na2CO3 and ClO2 was studied. Furthermore, tests for the thermal stability, the influence of different factor on the activation and the disinfection effect on bacteria of the "stabilized chlorine dioxide" were carried out and compared with those of sodium chlorite and chlorine dioxide solution. The results show that chlorine dioxide and carbonate exist as the pattern of ClO2- and HCO3- in the "stabilized chlorine dioxide" solution, respectively. It was proved that ClO2 had reacted with H2O2 and Na2CO3 in the "stabilized chlorine dioxide" solution and produced chlorite ClO2- and bicarbonate HCO3-, and given off O2 by oxidation-reduction/proton transport reaction. So it was believed the so called "stabilized chlorine dioxide" is a mixture of ClO2- and HCO3-.
