摘要
综述了石英在纯水、电解质和有机酸溶液中的溶解动力学实验技术和研究成果，着重阐明了电解质浓度、离子强度、ＰＨ、阳离子和有机酸对石英溶解的动力学促进作用，并指出这种催化效应与石英表面负电性络合物的反应性有关。
This paper summarizes the experimental methods and results ofdissolution kinetics of quartz in pure water,electrolyte and organic acid solutions from literature.It is concluded that the dissolution rate of quartz can be enhanced by alkali cations, organic acids and increasement of electrolyte concentration,ionic strength and pH,and such catalysis effects are mainlyrelated to the reactivity of the negative-chargedsurface complex of quartz.
