| 摘 要： | 用乙二胺四乙酸二钠(EDTA)对二氧化氯进行稳定化实验,使用紫外分光光度法检测二氧化氯的浓度,测定了反应物之间的化学计量关系,分析了酸度对EDTA的影响,根据EDTA配合物的结构提出两者不可能形成配合物而是发生了氧化还原反应,并据此解释了化学计量关系、红外图谱、二氧化氯释放等实验现象.

| Abstract: | The stabilization of ClO2 has been tested with ethylenediamine tetraacetic disodium salt(EDTA).The concentration of ClO2 is determined by UV spectrophotometry and the stiochiomic relationship between ClO2 and EDTA has been studied.Based on the effect of pH on EDTA and the coordination compound struction of EDTA,it is impossible for EDTA and ClO2 to form redox reaction rather than coordination compound as other researchers reported.The redox reaction of EDTA and ClO2 could explain the experimental results of infrared spectrometry,the release of ClO2 and the stiochiomic relationship between EDTA and ClO2. |
