| 内容記述 | The pure strontium sulfate was precipitated by the reaction of strontium ion and kinds of precipitants ((NH_4)_2SO_4, NH_4HSO_4, Na_2SO_4, K_2SO_4, MgSO_4, CdSO_4,CaSO_4) in aqueous solution at 100℃. These experimental methods were the same means as our previous papers. The concentration of precipitants (expect CaSO_4) was equimolar against the strontium ion, respectively. The amounts of strontium sulfate precipitate deposited and strontium ion in aqueous solution were also determined by the several analytical methods reported in the preuous papers. The deposited percentage values of strontium sulfate precipitate obtained by the afore experiments represented the high yields (almost approximately 86%) through all the various reaction periods. In the case of sulfamic acid as precipitant, they became very large with increase of the reaction times and the concentrations. Therefore, these values obtained afore by equimolar reaction were smaller than the former values, but similar values to the case of the former were obtained by double molar reaction and at the long reaction times. And then, the former values were compared with the deposited percentage values of strontium sulfate in obtained precipitates by KCP reaction by using of the various carriers (barium ion, lead ion, lead sulfate precipitate). The growth process of particles of the strontium sulfate precipitate obtained by the various kinds of precipitants were observed by using of an optical microscope and photographs. The results obtained by the microscope showed in micrographs. The size of both particles of strontitim sulfate precipitate obtained by this experiment and KCP reaction experiment became very large with increase in the reaction times. The shapes of the former particles were observed various shapes (oval, rectangular, lozenge, hexagonal type and spherical gathering type of needle- or wedge-shaped particles). On the other hand, almost all shapes of the latter particles were observed as clear crystals of rectangular type. | |||||||
