摘要：

Sodium hydroxide is added to the sodium carbonate solution used for the selective removal of silicon from silica-rich zeolites. This adjusts the initial pH of the suspension for a more efficient desilication process. As a general rule, the higher the Si:Al ratio of the zeolite, the lower is the pH of the desilication medium.
