Procedure

267.1 g of the aqueous sodium zincate solution prepared in Preparation Example 5 and 86.9 g of sodium stannate (Na2SnO3 ·3H2O, manufactured by Showa Kako K.K., containing 55 wt % as SnO2) were dissolved in 2,063.1 g of water, to obtain an aqueous solution of sodium zincate/sodium stannate mixture (containing 1.02 wt % as ZnO, containing 1.98 wt % as SnO2, ZnO/SnO2 molar ratio: 0.95). Thus, 2,417.1 g of an aqueous solution of sodium zincate/sodium stannate mixture, was prepared. Separately, 295.7 g of 35 wt % hydrochloric acid was dissolved in 1,991.9 g of water, to obtain 2,287.6 g of an aqueous hydrochloric acid solution.
