Method for synthesizing sodalite zeolite molecular sieve from granite weathered residual soil

Abstract

The application discloses a method for synthesizing sodalite zeolite molecular sieve by taking granite weathered residual soil as raw material, and relates to the technical fields of solid waste resource utilization and inorganic functional material. The method for synthesizing sodalite zeolite molecular sieve by taking granite weathered residual soil as raw material comprises the following steps: purifying the granite weathered residual soil to obtain clay powder; performing ball milling treatment on the clay powder to obtain mechanically activated material; mixing the mechanically activated material with sodium hydroxide solution, and then performing reaction at 50-80 DEG C for 6-24h to obtain reaction synthesis; and sequentially washing and drying the reaction synthesis to obtain the sodalite zeolite molecular sieve. The application can realize the purpose of resource utilization of the granite weathered residual soil, and the synthesis method has the advantages of low reaction temperature, simple synthesis process and normal pressure, and solves the problems of high energy consumption and complicated process of the traditional method for preparing the sodalite zeolite molecular sieve.
