摘要

The use of 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) as a weed killer has led to its being one of the most frequent components of wastewater, with substantial environmental and public health implications owing to its toxicity and bioaccumulation. Traditional water treatment plants do not effectively remove 2,4,5-T, necessitating the development of more efficient and environmentally friendly alternatives. Among the various technologies, adsorption has proven to be a superior and economical removal technique for 2,4,5-T due to its ease of use, high efficiency, and renewability. This article reviews recent developments in the removal of 2,4,5-T from wastewater by adsorption, materials, mechanisms, and parameters. The effects of physicochemical conditions on adsorption activity were also discussed in this study. Furthermore, we discuss catalytic dehydrochlorination and advanced oxidation techniques as complementary options for increasing the removal efficiency of 2,4,5-T. Finally, it discusses future challenges and research on optimizing adsorption efficiency and large-scale applications. This review provides information on optimizing adsorption technology to effectively remove 2, 4, 5-T from contaminated water bodies.
