Abstract
Trithionate potassium was synthesized by oxidation of hydrogen peroxide with thiosulfate.With the temperature of 4—10℃ and after the re-crystallizing with anhydrous ethanol,the product's yield and purity were 71.4% and 98.46% respectively.The structure of the product was confirmed by FTIR and CE,the concentration of trithionate potassium was tracked and detected at high pH by capillary electrophoresis.The results showed that the character of trithionate potassium was relatively stable,and decomposition rate is slower at pH13.As the pH increased,the decomposition rate of trithionate became faster.
