摘要
electrolysing the electroyte composition containing 50- 100 g/1 lead and 70-120 g/1 fluoboric / fluosilicic acid at a current density of 170-400 A/m2 employing graphite or Titanium Substrate Lead Dioxide (TSLD) as anode material and cathode material selected from stainless steel, lead or titanium with the addition of 3.0-5.0 g/1 grain refiner, 40-1000 ppm leveling agents such as herein described, 500-3000 ppm lead dioxide inhibiting agents such as soluble arsenic or phosphorous compounds, recovering the lead deposited on cathode by known method..
