摘　　要：Far-ranging and improper uses of pharmaceuticals and personal care products(PPCPs)over the last few decades have led to severe water contamination that imposes serious effects on human beings and the ecological system.Therefore,there is an increasing demand for a highly-efficient and environmentally friendly technology for the removal of PPCPs from aqueous solutions.Adsorption technology is an appropriate technology to solve this issue.Carbon-based composites,ranging from modified activated carbon to functionalized biochar,show great potential for this purpose.This review hence elaborates on the environmental occurrences and risks of PPCPs and summarizes the recent progress in removing PPCPs from water using carbon-based adsorbents.The pore structure,relatively large specific surface area(SSA),abundant surface functional groups,highly aromatic structures and the extra excellent characteristics of the cooperative materials contribute to their outstanding adsorption performance.Furthermore,the biochar-clay material is cost effective and more efficient compared to traditional activated carbon regarding the adsorption of PPCPs.Among the emerging adsorbents,graphene and carbon nanotubes composites show superior adsorption ability.Their adsorption mechanisms,such as electrostatic interactions,hydrogen bonding,and pore filling,are discussed in details.
