【摘要】 溶液的介稳区宽度是结晶过程的基础研究之一。实验测定了纯磷酸二氢钠溶液在不同饱和温度下的介稳区宽度及25℃时含有杂质的磷酸二氢钠溶液的介稳区宽度,同时考察了pH值和降温速率对溶液介稳区宽度的影响。介稳区宽度的测定结果对指导磷酸二氢钠的结晶过程有参考价值。更多还原

【Abstract】 MZW of solution crystallization is a part of the basic study contents. The crystallization MZWs of both pure sodium dihydrogen phosphate saturation solution at different temperature and sodium dihydrogen phosphate saturation solution impurities-containing at 25 ℃ are determined. Meanwhile,the effects of both pH value and cooling rate on crystallization MZW of sodium dihydrogen phosphate are also studied. The results play a reference for the guide on crystallization of sodium dihydrogen phosphate.更多还原
