【摘要】 <正>多氯联苯(PCBs)在水体中含量低,不易被发觉,然而PCBs具有生物放大和累积性,在环境中通过食物链的传递,易给人体产生极大的生理毒性作用。因此对PCBs的痕量与超痕量分析研究对于当今环境安全分析领域具有重要意义。更多还原

【Abstract】 Polychlorinated biphenyls(PCBs) are importantly strong carcinogenic persistent organic pollutants,and their concentration are very low in water.It’s very important to select appropriate pre-treatment methods to achieve the separation and enrichment of trace PCBs in complex environmental samples,which is important for the speciation and toxicity study of PCBs.our groups have developed a novel SPE method based on mixed ionic surfactants modified CNTs,where magnetic nanoparticles are adsorbed on ionic surfactants to form magnetic nanoparticles(MNPs).Compared with traditional solid-phase extraction(SPE) sorbents,the magnetic property endues the sorbents with magnetic separation ability so that the time-consuming SPE can be facilitated.更多还原
