去除水体中PPCPs的4种改性新型吸附材料研究进展

Research progress of four new modified adsorbents for removal of PPCPs in water

近年来,药品及个人护理用品(PPCPs)的环境污染问题日益严重。虽然这些污染物在水体中的浓度很低,但由于其结构复杂、可生化性差,对生态环境乃至人体健康产生危害。吸附分离是一种简单、快捷、高效去除水体中PPCPs的方法。分别综述了用于水体中PPCPs分离的4种深受学者关注极具发展潜力的吸附材料[生物炭、石墨烯、金属有机框架(MOFs)、层状双金属氢氧化物(LDH)]的研究进展,重点介绍了它们改性复合的方法和改性复合后对PPCPs的吸附性能,最后探讨了4种新型吸附材料的优缺点,提出了未来深入研究的方向。

In recent years,the environmental pollution of pharmaceuticals and personal care products(PPCPs)has become increasingly serious.Although their concentration in water is very low,they are harmful to the ecological environment and even human health due to complex structure and low biodegradability.Adsorption separation is a simple,fast and effective method to remove PPCPs from water.Four new adsorption materials for PPCPs separation in water,including biochar,graphene,metal-organic frameworks(MOFs)and layered double hydroxide(LDH)which have attracted much attention were reviewed.The capacity of adsorbing PPCPs after modified and composited were mainly introduced.Finally,the advantages and disadvantages of the four new adsorption materials were discussed and the future research direction was put forward.
