Application of Magnetic Composites in Removal of Tetracycline through Adsorption and Advanced Oxidation Processes (AOPs): A Review

Abstract

Water pollution induced by the tetracycline (TC) has caused global increasing attention owing to its extensive use, environmental persistence, and potential harm for human health. Adsorption and advanced oxidation processes (AOPs) have been promising techniques for TC removal due to ideal effectiveness and efficiency. Magnetic composites (MCs) which exploit the combined advantages of nano scale, alternative sources, easy preparation, and separation from wastewater are widely used for catalysis and adsorption. Herein, we intensively reviewed the available literature in order to provide comprehensive insight into the applications and mechanisms of MCs for removal of TC by adsorption and AOPs. The synthesis methods of MCs, the TC adsorption, and removal mechanisms are fully discussed. MCs serve as efficient adsorbents and photocatalysts with superior performance of photocatalytic performance in TC degradation. In addition, the TC can be effectively decomposed by the Fenton-based and SO4•− mediated oxidation under catalysis of the reported MCs with excellent catalytic performance. Based on the existing literature, we further discuss the challenge and future perspectives in MCs-based adsorption and AOPs in removing TC.

“…17a and b). 128 b However, a better adsorption capacity of a MOF has been reported by Hu et al They have modified Cr-MOF, 128 c which is found to detect tetracycline specifically in the presence of FeSO 4 , which is used as a masking agent. SEM measurement of the modified MOFs indicated that nZVI is evenly coated on the MIL-101 surface.…”

“…Tetracyclines (TCs) are antibiotics that are broadly used for their antibacterial activity. 128 a Specifically, they are used for the antibacterial treatment of the urinary tract and respiratory system. TCs are used as an additive in food systems and found in many foods.…”

“…This problem is monitored using a Tb-based MOF having the formula [Tb(sbdc) 1.5 (H 2 O) 2 ]. 128 a It has been found that in the presence of Na 2 SO 4 as a masking agent, MOFs are able to detect TCs specifically over other antibiotics with a detection limit of 0.28 μL to 0.30 μL. It is known that the aromatic compound can be easily adsorbed on GO and graphene by π–π stacking.…”

“…Among the commonly used antibiotics, tetracycline (TC) is the most widely used in aquaculture and pharmacy due to the relatively low costs [ 3 , 4 ]. Unfortunately, TC is a typical sterilizing medicine, which is excreted in the form of original drug or parent compounds for humans or animals, and is subsequently discharged into the environment [ 5 , 6 ]. As a result, TC has been detected in wastewater, surface and groundwater, and these trace amounts of TC could cause adverse consequences.…”

Efficient ZnCr LDH/monoclinic‐WO3 composites for Degradation of Tetracycline under Visible Light

“…Presence of TC in water bodies is presently a subject of incredible concern. In recent years, various techniques like adsorption, electrolysis, microbial degradation, and photodegradation have been devoted for the removal of TC and other harmful pollutants from wastewater [8–11] . Among these methods, photocatalysis is one of the most encouraging advancements because of its great effectiveness, eco‐friendly nature, and easy operation [12–15] .…”
