摘要
铊及其盐类是一类环境危害性极强的水体污染物,甚至低浓度的铊都会对生命体产生严重的毒害作用。在对铊的理化性质、用途及污染现状简单评述的基础上,综述了目前水体中铊常用的污染治理技术如吸附法、化学沉淀法、离子交换法、溶液萃取法等及其优缺点,并重点评述了活性炭、纳米金属氧化物、生物材料及复合材料等吸附剂用于吸附水体中铊的性能及其优缺点。最后对水体中铊的污染治理领域的未来研究热点及应用前景作了展望。
Thallium and its compounds are highly hazardous environmental pollutants for water bodies. Thallium is fatal to living organisms even at trace level and its efficient removal from receiving water is still a challenging task. In this paper, physical and chemical properties, application, pollution of thallium were introduced simply, hereaftertreatmenttechnologiesforthallinmpollutionofwaterswerereviewed,includingadsorption, chemicalprecipitation, ion exchange and solvent extraction. The adsorbents such as activated carbon, nanosized metal oxide, biomaterials and composite materials, whose properties for removing thallium from polluted waters were presented. Finally, the development trend of treatment technologies with thallium pollution was evaluated.
