摘要: 本文根据实际生产的需要,详细地研究了杂质Li+对K2SO4结晶过程的影响,并结合理论分析。计算了杂质Li+对K2SO4结晶过程中成核特征的影响.结果表明,Li+改变了体系的比表面自由能δ12、成核势垒△G(r*),使亚稳区宽度增加.

关键词: 杂质影响, 亚稳区, 硫酸钾水溶液, 结晶

Abstract: The effect of Li+ ion on the metastable zone width and the nucleation characteristic parameters of K2SO4 aqueous solution were invesigated.It was found that the metastable zone widths were increased in the presence of Li+ .The influence of Li+ on the metastable zone width may be a result of its effect on the specific surface energy δ12 and the nucleation energy G(r*).

Key words: Effect of Li+ ion, Metastable zone, K2SO4 aqueous solution, Crystallization
