【摘要】 通过浊度法测定10℃～45℃范围内MgSO4-H3BO3-H2O体系中硼酸的溶解度及介稳区宽度,得到硼酸的成核方程,并计算其表观成核级数。实验结果表明,硫酸镁的存在降低了硼酸的溶解度;随着硫酸镁浓度的升高,硼酸的介稳区宽度先变宽后变窄;硫酸镁的加入使硼酸的表观成核级数增加。更多还原

【Abstract】 The solubility and metastable zone width of boric acid in MgSO4-H3BO3-H2O system were determined in the temperature range from 10 ℃ to 45 ℃ by turbidity method,the formulas of nucleation were obtained and the apparent nucleation orders of boric acid were calculated.The results showed that,the presence of magnesium sulfate decreases the solubility of boric acid;The metastable zone width of boric acid first becomes wider and then narrower with increasing concentrations of magnesium sulfate;the addition of magnesium sulfate increases the apparent nucleation orders of boric acid.更多还原
