Abstract: The recycling technology of mother liquid in the synthesis of zeolites is a new method for the preparationof zeolites, which can effectively improve the utilization rate of raw materials and reduce the discharge of waste liquid. In this article, the generation and composition of mother liquidof zeolitesynthesiswas introduced, the recycling technology of mother liquid of zeolite synthesisand its application in zeolite synthesis were briefly described, and the research progresses of this technology focused on the synthesis of the most representative zeolites including Y, ZSM-5, SAPO-34 as well as other zeolites were summarized. In addition, the challenges faced by the recycling technology of mother liquid of zeolitesynthesiswere also proposed.Based on this, the development direction of this technology in industrial production was envisioned. This research would provide reference for achieving the efficient and sustainable development of zeolite industry.

Key words: zeolite, mother liquid, recycling technology, sustainable synthesis
