多孔材料在重金属离子汞吸附中的研究进展

Research Progress of Porous Materials in the Adsorption of Heavy Metal Ions and Mercury

汞是一种普遍存在于地球生态系统中的物质,它会通过水的流动、土壤的变化、空气的传播及生物体的吸收来转移并转化为新的形态。当人们因为饮用受汞污染的水源、食用含有汞的食物或者直接暴露于含汞的环境时,就会引发各种疾病。其中,吸附富集的测定方式有助于降低方法检出限,提高检测结果的稳定性与准确度,而一般性富集前处理方式为吸附与洗脱,主要简述了在重汞检测领域样品前处理中采用由相互贯通或封闭的孔洞组成的网络状结构新型多孔材料的研究进展。

Mercury is a ubiquitous substance in earth's ecosystems and is transferred and transformed into new forms through water flow,changes in soil,airborne transport,and absorption by living organisms.When people drink mercury-contaminated water,eat food containing mercury,or are directly exposed to environments containing mercury,various diseases can occur.Among them,the measurement method of adsorption and enrichment helps to reduce the method detection line and improve the stability and accuracy of the detection results,while the general enrichment pre-treatment method is adsorption and elution.This article mainly briefl y describes the heavy mercury detection field.Research progress in using new porous materials with a network structure composed of interconnected or closed pores in sample pretreatment.
