The pattern of ClO2 stabilized by Na2CO3/H2O2

Abstract In this paper, the existing patterns of carbonate and ClO 2 in the so-called “stabilized chlorine dioxide” solution which is stabilized by stabilizers Na 2 CO 3 and H 2 O 2 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 NaClO 2 and ClO 2 . The results show that ClO 2 in “stabilized chlorine dioxide” solution exists in the form of chlorite ClO 2 − , carbonate exists in the form of bicarbonate. Therefore, it is considered that “stabilized chlorine dioxide” solution is mixed solution of ClO 2 − and HCO 3 − , its pH being 8.5.
