Abstract
The process comprises treatment for 3 minutes at 40-110 degrees C in electrolyte containing phosphoric acid 20-95, sulphuric acid 5-80 and amino methylated polyacrylamide 0.1-20 per cent. The current density is 15-60 A/dm2, and the lead cathode decreases costs by 50 per cent compared with the conventional process. The acid densities are ca. 1.71 and 1.83 g/cm3 respectively, and the amide is in the form of 1-15 per cent solution in water.
