ABSTRACT
As a non-steroidal anti-inflammatory drug, naproxen is widely used worldwide. According to the previous investigation and statistics, naproxen has been detected in various environmental media with a concentration of ppt-ppb level, but its environmental risk should not be underestimated. Three types of naproxen removal technologies in the water environment, including physical, chemical and biological technologies, have been reviewed in this paper. Efficient removal methods have been developed in each type of removal technology, but each type has its defects to be solved. This paper further discusses the influence of pH on various removal technologies. Many studies have shown that pH affects naproxen removal in the aqueous phase, and acidic conditions are more conducive to the effective removal of naproxen.
