摘　　要：首先通过理论分析 ,认为二氧化氯 (ClO2 )在稳定性二氧化氯溶液 (简称稳定液 )中存在的形态根据所用稳定剂的不同而有区别。通过对几种样品的红外光谱分析、纸色谱分析、酪氨酸显色反应及抗酸缓冲能力的测定 ,证实在以过碳酸钠为稳定剂的稳定液中 ,ClO2 以亚氯酸根离子 (ClO2 -)形式存在 ,并处在一个由NaHCO3 -Na2 CO3组成的缓冲体系中 ;在以过硼酸钠为稳定剂的稳定液中 ,ClO2 可能是以活性配位化合物的形式存在 ,并处在由H3 BO3 -Na2 B4 O7组成的缓冲体系中。这一结论对稳定性二氧化氯溶液的生产。Firstly depending on theoretical analysis,this paper suggests that chlorine dioxide(ClO 2) in stabilized chlorine dioxide aqueous solution(stabilized solution) has a different existence form because of the different stabilizer used. On the basis of the analytical results of infrared spectrometry,paper chromatography,tyrosine color development reaction and the assay of anti acid buffer capability,we confirm that chlorine dioxide in stabilized solution with sodium percarbonate as stabilizer exists in the form of chlorition (ClO 2 -) and exists in NaHCO 3-Na 2CO 3 buffer system. When the stabilizer is sodium perborate,chlorine dioxide may be retained in the solution comprised of H 3BO 3-Na 2B 4O 7 as a labile complex. The results related above will have important guide effect on product,store and application of stabilized chlorine dioxide solution.
