海水为溶剂合成纳米粉煤灰沸石及其性能表征
Synthesis and characterization of nano-fly ash zeolites made using seawater for crystallization
摘要
Abstract
Nano-fly ash zeolites were synthesized using fusion method with seawater as solvent. The synthetic conditions were as follows： ash/NaOH quality ratio is 1：1.2, fusion temperature is 550℃, the mixture/seawater volume ratio is 1：5, reaction temperature is 100℃ and reaction time is 6h. The structure, appearance and properties of the products were characterized and analyzed in detail with both instrumental and chemical analysis methods. In addi- tion, the mineral composition, crystallization, surface area, capacity of the cation exchange, average particle size and chemical composition of synthesized zeolites were investigated and compared. The results showed that the product is a mixture of NaX zeolite and hydroxysodalite. This synthesized zeolite by fusion method using seawater for crystallization has higher purity and better crystallization than that by conventional hydrothermal method. The properties and characters of this synthesized zeolite show that it has good application values.关键词
