摘要
综述了近年来脱氯吸附剂的研究进展,分析了活性炭、分子筛、金属氧化物等吸附剂的优缺点。其中分子筛和金属氧化物吸附剂显示出了良好的脱氯性能,且可通过简单的空气热处理再生,是非常有前景的脱氯吸附剂。在升高温度的情况下,分子筛和金属氧化物对有机氯的吸附从物理吸附转为化学吸附,脱氯性能显著提升,因而分子筛和金属氧化物化学吸附脱氯将是未来研究的热点。
The various dechlorination adsorbents developed in recent years are reviewed,and the advantages and disadvantages of various dechlorination adsorbents,such as activated carbon,molecular sieve and metal oxides are analyzed. Molecular sieves and metal oxide adsorbents not only show good dechlorination properties,but also can be regenerated by simple air heat treatment,and thus are very promising dechlorination adsorbents. It is worth noting that in the case of elevated temperature,the adsorption of molecular sieves and metal oxides on organic chlorine transforms from physical adsorption to chemisorption,and the dechlorination performance is signi?cantly improved,and dechlorination by chemisorption will be a hot spot in future.
