As a continuation of the previous paper, the results of the examination on the influence of further operating parameters (anodic current density, anodic current concentration, molar ratio of the starting solutions, P0 = m0[H2SO4] / m0[(NH4)2SO4], conversion degree, a = m[(NH4)2S2O8] / m0[(NH4)2SO4], composition and form of the anodic material, nature and concentration of anodic additives) on the anodic current efficiency χ and cell voltage of the laboratory flow-through integral electrolyzer model of the monopolar type were presented and discussed. The obtained results may be used for the optimization of the operating conditions of the industrial persulfate electrolyzer of the monopolar as well as bipolar type, too.
