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-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。这一结论对稳定性二氧化氯溶液的生产、贮存和应用具有重要的指导作用。

First ly depending on theoretical analysis, this paper suggests that chlorine dioxide(ClO₂)in stabilized chlorine dioxide aqueous solution(stabilized solution)has a different existence form because of the dif ferent stabilizer used.On the basis of the analy tical results of inf rared spectromet ry, paper chromatog raphy, tyrosine color development reaction and the assay of anti-acid buffer capability, we confirm that chlo rine dioxide in stabilized solut ion wi th sodium percarbonate as stabilizer exists in the form of chlorition (ClO₂ -)and exist s in NaHCO₃ - Na₂CO₃ buffer system.When the stabilizer is sodium perborate, chlorine dio xide may be retained in the solut ion comprised of H₃BO₃ -Na₂B₄O₇ as a labile complex.The results related above w ill have impo rtant guide ef fect on product, sto re and application of stabilized chlorine dioxide solution.
