A Review on Application of Biochar in the Removal of Pharmaceutical Pollutants through Adsorption and Persulfate-Based AOPs

Increasing quantities of pharmaceutical pollutants have been found in aquatic ecosystems. The treatment has a major task that people committed to recent years. removal can be achieved by adsorption and advanced oxidation processes (AOPs). Compared with other carbon materials, biochar strong capacity persulfate activation ability, more importantly, is cheap easy obtain; thus, it higher economic benefits. This study firstly reviews the application drugs (tetracycline (TC), sulfamethoxazole (SMX), acetaminophen (ACT), cephalexin (CPX), levofloxacin (LEV), etc.) through persulfate-based AOPs. In addition, we summarize mechanism for various main attack sites on different AOPs catalyzed biochar. Finally, challenges prospects respect are put forward.
