水滑石类材料及其对水中阴离子污染物的吸附

Hydrotalcite Like Materials and their Adsorption of Anionic Contaminants

水滑石类材料,是一类由带正电荷层和层间填充带负电荷的阴离子所构成的层状化合物,因其独特的催化和吸附性能成功应用在化工、医药、农药、功能材料等领域,近年来,水滑石材料在环境领域的应用逐步成为研究热点,此类材料对水中无机阴离子、络合阴离子形式重金属离子、阴离子染料和阴离子表面活性剂有较强的吸附能力,显示出良好的应用前景。

Hydrotalcite like materials was a positively charged layers and filled with the negative charge of the anionic form layered compounds,due to their unique catalytic and adsorption properties of successful and wild application in the chemical,pharmaceutical,pesticide,functional material. In recent years,the application of hydrotalcite like compounds in environment field gradually became a research hotspot,anion,such materials in water inorganic anion forms of heavy metal ions,anionic dyes and anionic surfactants had stronger adsorption ability,with a good application prospect.
