Optimization of synthesis parameters for the preparation of zeolite by reusing industrialwaste as raw material: Sandblasting waste and solar panel waste glass.

This paper describes the use of sandblasting waste (SW) and solar panel waste glass (SPWG) as raw materials in the hydrothermal synthesis of Linde-type A zeolite (zeolite A) with crystallinity (83.89%) matching that of samples in the literature. ANOVA results indicated the following optimal synthesis parameters: crystallization temperature (120 °C), crystallization time (36 h), and Si/Al molar ratio (SAMR = 2.0). Model fitting results (R2 = 0.94) revealed a strong correlation between our regression results and experiment results, with the P value meeting the 95% confidence level. Experiment results confirmed the efficacy of the proposed hydrothermal processing method in synthesizing zeolite A using SPWG and waste SW as raw materials. [Display omitted] • Zeolite A (SZ) synthesized from solar panel waste glass and sandblasting waste. • Achieving the crystalline SZ with crystallinity of 83.89% at 120 °C and 36 h. • Model fitting results (R2 = 0.94) revealed a correlation between regression results and experiment results. • This study explains the crystallization mechanism of zeolite A synthesized from waste materials. • All major components of solar panel waste glass and sandblasting waste were utilized fully.
