添加晶种的kno3水溶液间歇结晶动力学模型
DOI: 10.3969/j.issn.1671-7627.2003.03.003, PP. 12-16
Keywords: 间歇结晶,二次成核,动力学模型,透光率,动力学参数
Abstract:
针对添加晶种的二次成核结晶过程的特点,并基于beer-lambert定律、δl定律和粒数衡算理论,建立了包含透光率变量的间歇结晶动力学模型.运用该模型对kno3水溶液冷却结晶实验的溶液质量分数、相对过饱和度以及透光率数据进行关联,一次性获得了结晶体系的二次成核和生长动力学参数,其值与文献值吻合较好.尝试以光学法关联动力学模型的研究,将有助于结晶机理的深入认识,为动力学模型的进一步发展提供思路.
