摘要
本文综述了利用工业废弃物-粉煤灰合成沸石分子筛的最新进展,包括水热法、两步法、碱熔融法等合成工艺,评价了各种合成方法的特点及存在的问题,并对粉煤灰合成沸石分子筛在化工行业、水处理、废气治理以及放射性废物处理等领域的最新应用进展进行了介绍,展望了粉煤灰合成沸石分子筛的研究及应用前景。
The studies on zeolite synthesis from coal fly ash （ CFA）, including the methodologies such as classic hydrothermal process, two-step process, molten-salt process, the characteristics and disadvantages of these methods are evaluated. In this paper, the research field in the future about zeolite synthesis from coal fly ash and its potential applications in environment are also viewed, including chemical agents, water treatment, emissions disposal and radioactive waste.
