Efficient removal of dibutyl phthalate from aqueous solutions: recent advances in adsorption and oxidation approaches

Abstract

Dibutyl phthalate (DBP), a recognized endocrine-disrupting contaminant, poses substantial environmental challenges due to its persistence, resistance to degradation, and potential for bioaccumulation. Hence, efficient removal technologies for eliminating DBP from water are receiving increased attention. This review assesses the effectiveness of adsorption and oxidation methods for DBP removal, including the utilization of carbon-based materials, molecularly imprinted polymers (MIPs), photocatalytic oxidation, and conventional oxidation employing oxidants such as persulfate and ozone. The mechanisms governing the processes of adsorption and oxidation are elucidated. Additionally, current challenges and future prospects are also addressed, aiming to provide valuable insights into the removal of DBP from real-world wastewater and the purification of water resources.
