Abstract

Abstract: The electrochemically activated persulfate process has been demonstrated to enhance the efficacy of the degradation of unsymmetrical dimethylhydrazine (UDMH) in wastewater. The concentration of UDMH was typically determined through amino sodium ferrocyanide spectrophotometry. Nevertheless, the lengthy chromogenic reaction time and intricate operational procedure impede the efficiency of the analysis. The utilization of solution conductivity and temperature as indicators to ascertain the extent of UDMH degradation can enhance the efficiency of the analytical process. The impact of varying voltage, initial pH, ionic strength, Na₂S₂O₈ dosage, circular flow, and UDMH concentration on the observed patterns of UDMH concentration, pH, solution temperature, and conductivity were investigated. A correlation was identified between the transition points for the rapid and gradual changes in conductivity and temperature, which occurred five minutes earlier than those observed in the UDMH concentration and pH. During the sampling process, the degree of UDMH removal can be predicted online by monitoring the solution temperature and conductivity, thereby reducing the duration of the test and enhancing the efficiency of the analysis.
