摘要
鉴于石英溶解对全球变化和环境影响的重要性,其机理的研究成为近来地学领域比较活跃的课题。许多学者从物理、化学,甚至生物学的角度研究了石英溶解的机理。本文从pH值、温度、离子强度和表面形态四个方面综述石英溶解机理的研究进展。前人的研究成功地解释了石英-水在不同条件下的溶解机理,成功地解决了溶解动力学相应的单个参数问题。但是,石英溶解的条件非常复杂,往往是多个因素共同作用的结果,因此只研究单个参数的影响无法真正了解矿物溶解的动力学机理。石英溶解机理需要探索实验和理论方面更深层次的问题。
Quartz dissolution study is an active area in geoseiences today because it is important to the study of global change and environmental issues. Many researchers studied the driving forces of quartz dissolution from the aspects of physical, chemical and even biological ways. This article reviews the recent progresses on quartz dissolution mechanism studies, especially focusing on the influence factors, such as pH, temperature, ionic strength and surface morphology. The previous research has explained the dissolution mechanisms of quartz-water under different conditions,which is very successful in single parameter dissolution kinetics. On the other hand, the conditions of quartz dissolution are very complicated and the results often depend on a number of factors. It is impossible to really understand kinetic mechanism of mineral dissolution if only a single parameter is considered. A successful mechanism study of quartz dissolution needs further explorations from experimental and theoretical aspects.
