研究了用氧还原法制备过氧化氢稀溶液的方法。在h型双室反应器的初步实验中，确定了最合适的条件如下：反应温度为288 K，阴极为石墨，阳极为镍，阴极为1 mol•dm-3 KCl + 0.01 mol•dm-3 NaOH溶液，阳极为1 mol•dm-3 NaOH溶液。在石墨颗粒填充床电极反应器中，生成过氧化氢的速率和电流效率取决于初始床层过电位、反应器内液体流速和阴极液槽内氧流速。在极限电流条件下，通过模型分析明确了初始床层过电位为- 0.4 V时过氧化氢的产率。
The method for producing a dilute solution of hydrogen peroxide by reduction of oxygen was examined. In preliminary experiments with an H-type dual-compartment reactor, the most suitable conditions were determined to be as follows. The reaction temperature was 288 K, the cathode graphite, the anode nickel, the catholyte 1 mol•dm-3 KCl plus 0.01 mol•dm-3 NaOH solution and the anolyte 1 mol•dm-3 NaOH solution. In the packedbed electrode reactor with graphite particles, the rate and the current efficiency of producing hydrogen peroxide were dependent on the initial bed overpotential, the liquid velocity in the reactor and the oxygen flow rate in the catholyte tank. The production rate of hydrogen peroxide at an initial bed overpotential of - 0.4 V was clarified by the model analysis under the limiting current condition.
