| 内容記述 | In the presence of the various concentrations of sulfamic acid, the pure and the mixed sulfates Of barium and lead ions are precipitated by the kinetically controlled precipitation (Precipitation from homogeneous solution) reaction. The concentrations of sulfamic acid are used for both those of barium and lead ions from equimolar to sufficient excess molar. The concentration ratios of barium ion to the various concentrations of lead ion are not changed variously. At the equimolar reaction, the precipitates of lead sulfate in the mixed precipitation are observed at the initial stage of reaction independent of concentrations of lead ion, but they are observed less than those of barium sulfate. That of barium sulfate increases at the initial stage of reaction, but it is insufficiently observed in the precipitation molar fraction (Fig. 10). At the simultaneous reaction, the quantity of lead sulfate in the mixed precipitates decreases at the initial stage Of reaction compared with the single reaction, but it increases at the following stage of reaction. The increasing of lead sulfate is due to the promotion of the precipitation reaction of lead sulfate by the precipitation of barium sulfate formed at the initial stage of reactions . The precipitation molar fractions of lead sulfate in the mixed precipitates obtained by the excess molar reaction become larger than the theoretical values with decrease in the concentrations of lead ion (Table 5). These fracnons grow larger with increase. In the concentrations of lead ion as in the case of the same excess molar concentrations of the sulfamic acid (Fig. 11). In this case, that fractions of barium sulfate become larger than lead sulfate from the start to the last of reaction periods. | |||||||
