邻苯二甲酸酯性质及碳纳米管对其吸附作用的研究进展

Research Progress on the Properties of Phthalate Esters and their Adsorption by Carbon Nanotubes

邻苯二甲酸酯是全球使用量最大的塑化剂,近年来引起了较多关注。碳纳米管具有较为特殊的结构与性质,它能吸附特定无机物和有机物,其中碳纳米管吸附有机物的过程是存在多种吸附位点的不均匀吸附,并受到众多因素的影响。碳纳米管吸附邻苯二甲酸酯会影响其在环境中的迁移及生物有效性,相关研究结果能够为风险评估和污染控制提供参考。

Phthalate esters are the most used plasticizers in the world and they have attracted more attention in recent years. Phthalate esters have been detected in the atmosphere, water, soil and biological environment. Meanwhile, carbon nanotubes have special structures and properties, which can adsorb specific inorganic and organic matters. The adsorption of organic matters by carbon nanotubes is the uneven adsorption of multiple adsorption sites, which is affected by many factors.Adsorption of phthalate esters by carbon nanotubes can affect their migration in the environment and their bioavailability. Relevant research results can provide reference for risk assessment and pollution control.
