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 (ClO2-) and exists in NaHCO3-Na2CO3 buffer system. When the stabilizer is sodium perborate,chlorine dioxide may be retained in the solution comprised of H3BO3-Na2B4O7 as a labile complex.

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-Na2CO3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H3BO3-Na2B4O7组成的缓冲体系中。
