用于吸附重金属的水凝胶专利分析

Analysis on the Matrixes of Hydrogels Used in Heavy Metal Absorption

水凝胶作为一种价格便宜、吸收能力优良的载体和吸收材料,表面存在一定量的离子基团,在重金属离子吸附处理领域具有光明的前景。本文对吸附重金属用水凝胶领域公开的专利进行了分类分析,吸附重金属用水凝胶按基体主要分为合成高分子类水凝胶、天然高分子及其衍生物水凝胶及其他种类水凝胶三大类,介绍了不同基体材料的吸附重金属用水凝胶的性能与特点,以期为重金属吸附领域提供有意义的参考。

As a kind of cheap carrier and absorption material with excellent absorption ability,hydrogel has a bright prospect in the field of heavy metal ion adsorption.In this paper,the published patents in the field of heavy metal adsorption hydrogels are classified and analyzed.According to the matrix,the hydrogels for heavy metal adsorption are mainly divided into three categories:synthetic polymer hydrogels,natural polymers and their derivatives hydrogels and other kinds of hydrogels.The performance and characteristics of the hydrogels for adsorption of heavy metals by different matrix materials are introduced in order to provide a meaningful reference for the field of heavy metal adsorption.
