Technical note the pattern of ClO2 stabilized by Na2CO3/H2O2.
In this paper, the existing patterns of carbonate and ClO2 in the so-called "stabilized chlorine dioxide" solution which is stabilized by stabilizers Na2CO3 and H2O2 are analyzed. Meanwhile, thermostability, UV absorption spectrum, specificity of the paper chromatogram, microstructure and ionic chromatogram of this solution were studied, and contrasted with pure NaClO2 and ClO2. The results show that ClO2 in "stabilized chlorine dioxide" solution exists in the form of chlorite ClO2-, carbonate exists in the form of bicarbonate. Therefore, it is considered that "stabilized chlorine dioxide" solution is mixed solution of ClO2- and HCO3-, its pH being 8.5.
