“…In addition, the reduction of Fe 3+ and Cu 2+ to Fe 2+ and Cu + was difficult in advanced oxidation processes (AOPs), which greatly limits the catalytic ability of catalyst. , Hydroxylamine (HA), an inorganic substance used to prepare oximes, − has been used to active oxidants (H 2 O 2 , PDS and PMS), showing good activation performance. , What is more, the addition of HA, has been proven to be an effective way for accelerating the cycle of Fe 3+ to Fe 2+ or Cu 2+ to Cu + in a homogeneous catalytic process. ,, In addition, previous reports suggest the combination of HA with Cu 2+ could produce O 2 •– and H 2 O 2 by reducing dissolved oxygen, and Fe 2+ could also generate O 2 •– by oxygen reduction in homogeneous catalytic process. , The following reactions describe the generation of ROS (reactions –). ,,,− Recently, superoxide radical (O 2 •– ) catches attention from the public for its potential to destroy highly toxic organic chemicals such as pesticides, dioxins, chlorinated solvents and other carcinogenic chemicals. , O 2 •– , as a reactive oxygen species, was found in photocatalytic reactions under visible light irradiation, magnetite nanoparticles activation persulfate process, reaction process of Fe 2+ and O 2 , and Cu 2+ /HA system. ,,, Thus, the CuFe 2 O 4 /HA system might also be an effective way to degrade SMX by heterogeneous generation of O 2 •– or other ROS. …”

A new potential oxidation process is provided by CuFe2O4/hydroxylamine (HA) system for degradation of antibiotics in water. The CuFe2O4/HA system can generate reactive oxygen species (ROS) for the degradation of sulfamethoxazole (SMX). The addition of radical scavengers, including benzoquinone (BQ) and catalase (CAT), inhibited the oxidation of SMX in CuFe2O4/HA system. Electron transfer in the CuFe2O4/HA system played a key function for the generation of ROS and the degradation of SMX. The main ROS, was the superoxide radical (O2 •–) mainly generated from adsorbed oxygen (O2(A)), which came from the oxidation of the lattice oxygen (O2– (L)) in CuFe2O4. The CuFe2O4/HA system was effectively applicable for a broad pH range (approximately 5–10). In addition, the activation mechanism for CuFe2O4/HA system was studied with the target contaminant SMX. Finally, the degradation pathways of SMX were proposed under the optimal conditions in CuFe2O4/HA system.

Atrazine is a kind of triazine herbicide that is widely used for weed control due to its good weeding effect and low price. The study of atrazine removal from the environment is of great significance due to the stable structure, difficult degradation, long residence time in environment, and toxicity on the organism and human beings. Therefore, a number of processing technologies are developed and widely employed for atrazine degradation, such as adsorption, photochemical catalysis, biodegradation, etc. In this article, with our previous research work, the progresses of researches about the treatment technology of atrazine are systematically reviewed, which includes the four main aspects of physicochemical, chemical, biological, and material-microbial-integrated aspects. The advantages and disadvantages of various methods are summarized and the degradation mechanisms are also evaluated. Specially, recent advanced technologies, both plant-microbial remediation and the material-microbial-integrated method, have been highlighted on atrazine degradation. Among them, the plant-microbial remediation is based on the combined system of soil-plant-microbes, and the material-microbial-integrated method is based on the synergistic effect of materials and microorganisms. Additionally, future research needs to focus on the excellent removal effect and low environmental impact of functional materials, and the coordination processing of two or more technologies for atrazine removal is also highlighted.

Atrazine, an herbicide used to control grassy and broadleaf weed, has become an essential part of agricultural crop protection tools. It is widely sprayed on corn, sorghum and sugar cane, with the attendant problems of its residues in agri-food and washing water. If ingested into humans, this residual atrazine can cause reproductive harm, developmental toxicity and carcinogenicity. It is therefore important to find clean and economical degradation processes for atrazine. In recent years, many physical, chemical and biological methods have been proposed to remove atrazine from the aquatic environment. This review introduces the research works of atrazine degradation in aqueous solutions by method classification. These methods are then compared by their advantages, disadvantages, and different degradation pathways of atrazine. Moreover, the existing toxicological experimental data for atrazine and its metabolites are summarized. Finally, the review concludes with directions for future research and major challenges to be addressed.
