摘要
本文研究了碱 (5 %NaOH ,m)与蒙脱石、石英的相互作用。蒙脱石和石英在碱的作用下发生溶蚀 ,溶蚀是一个可逆过程。在深入认识溶蚀过程的基础上 ,建立了蒙脱石与碱相互作用的动力学模型 (1)和石英与碱相互作用的动力学模型 (2 ) ,并在大量实验数据的基础上确定了相关的动力学参数。
This paper presented the result of a laboratory study on the reaction and its kinetics between montmorillonite?quartz and alkaline solution. The result indicated that montmorillonite subjected to corrosion and produced SiO 3 -2 and AlO 2 - ions in the alkaline solution. The reaction between montmorillonite?quartz and alkaline solution is a reversible. The concentrations of SiO 3 -2 and AlO 2 - in the alkaline solution would be equilibrium value after a long reaction time. Two kinetic models of the reaction between montmorillonite?quartz and alkaline solution were presented. The data calculated by these kinetic models were conformable to that determined by experiments.
