摘要
研究杂质Cr3+对K2SO4结晶过程的影响，并计算在杂质Cr3+存在下K2SO4结晶过程中成核特征值的变化．结果表明，Cr3+改变了K2SO4的溶解度，使其亚稳区宽度变宽．
The effects of Cr3+ ions on the metastalbe zone width and the nucleation characteristic parameters of aqueous K2SO4 solution were investigated. It was observed that the solubilities werechanged and the metastable zone widths were increased in the presence of Cr3+.The influence of Cr3+on the metastable zone width may be the result of its effect on the nucleation and the rate of crystalgrowth.
