摘要：In order to improve current efficiency and decrease energy consumption in the electrosynthesis of ammonium persulfate, electrolytic properties of four cation exchange membranes, namely, the JCM-II (R) membrane, Nafion (R) 324 membrane CMI-7000 (R) membrane and a self-made perfluorosulfonic ion exchange membrane (PGN membrane) were investigated using a sintered platinized titanium anode and a Pb-Sb-Sn alloy cathode in a self-made electrolytic cell. The effect of cell voltage and electrolyte flow rate on the current efficiency and the energy consumption were investigated. The results indicated that the PGN membrane could improve current efficiency to 94.85% and decrease energy consumption to 1119 kWh t(-1) (energy consumption per ton of the ammonium persulfate generated) under the optimal operating conditions and the highest current efficiency of the JCM-II (R) membrane, Nafion (R) 324 membrane and CMI-7000 (R) membrane were 80.73%, 77.76% and 73.22% with their lowest energy consumption of 1323 kWh t(-1), 1539 kWh t(-1) and 2256 kWh t(-1), respectively. The PGN membrane has the advantages of high current efficiency and energy power consumption and has sufficient mechanical strength with the reinforced mesh. Therefore the PGN membrane will has good value in popularization in the industrial electrosynthesis of ammonium persulfate in the future.
