“…However, after a certain amount is exceeded, the active sites on the activators reach saturation and the degradation effect is no longer obvious. Besides, blindly increasing the amount of oxidant would not only reduce the pH of the system, but also lead to a waste of oxidant 47 . In addition, when the amount of oxidant is too much, the PMS will consume the free radicals and inhibit the decoloration effect 48–50 .…”

The discharge of colored textile printing and dyeing wastewater causes environmental pollution. The fading of wastewater efficiently, simply and with low consumption is a problem to be considered. Herein, a catalytic method for rapid decolorization of organic dyes was devised employing terpyridine iron complex to activate oxidized permonosulfate (PMS). CI Acid Red 1 (AR1) was used as the simulated pollutant, the influences of operating parameters on the fading effects of wastewater were explored. According to the results, the produced catalytic system exhibits a universal catalytic effect. Even when the dye concentration reaches 76.4 mg/L, the dyeing wastewater may be effectively decolorized. In addition, when anions (HCO3−, SO42−, Cl−) were present in the solution, the degradation effect of AR1 was still effective. Interestingly, active species such as sulfate radicals and singlet oxygen were detected in the catalytic degradation system by radical capture experiments. The total organic carbon (TOC) can reach a removal rate of 26.22% at 2 h. This research provides a unique enzyme‐like catalytic system for the rapid breakdown of dye contaminants.This article is protected by copyright. All rights reserved.

“…Previous literature has demonstrated that PMS can efficiently decompose various refractory organic matter, such as common dyes, endocrine disruptors, antibiotics, and cyanobactertoxins. [13] Moreover, the reactive oxygen species generated by PMS activation can target the bacterial cell membrane, altering its macromolecular structure and permeability. This leads to the release of essential enzymes, disrupting bacterial metabolism, mitosis, and other cellular processes, ultimately resulting in bacterial death.…”

To address global pollution caused by contaminants in water bodies, it is crucial to develop an efficient and environmentally friendly treatment process for wastewater from various industries. Advanced oxidation processes (AOPs) have proven to be highly effective in wastewater treatment due to their high oxidation efficacy and the absence of secondary pollutants. Different methods such as ozone, Fenton, electrochemical, photolysis, and sonolysis can be used in AOPs to degrade emerging pollutants that are resistant to conventional methods. In recent years, nanotechnology has emerged as a viable solution, with various nanomaterials being developed for wastewater treatment. Among them, copper‐based nanocatalysts have shown great potential in AOPs. This review focuses on the progress and mechanisms of copper‐based nanocatalysts in wastewater treatment via AOPs. It also discusses the challenges associated with oxidation, electrochemistry, Fenton, and photocatalysis in wastewater treatment processes.

“…It is very serious since PAHs can bring damage to people even at very low concentrations. It has strong carcinogenic, teratogenic, mutagenic, as well as phototoxic effects, which causes great harm to both environment and human [1,2]. PAHs have been listed as one of the most critical contaminants by the European Food Safety Authority (EFSA) and the United States Environmental Protection Agency (US-EPA) [3].…”

Magnetic graphene oxide-SiO2-TiO2 (MGST) composite was prepared for the absorption and further photodegradation of PAHs to reduce the risk of PAHs in the water environment. Magnetic graphene oxide (MGO) was obtained by introducing Fe3O4 to graphite oxide (GO). Furthermore, the suitable SiO2 layer was wrapped on the MGO for further modification with TiO2. Finally, the functional MGST composite with uniform morphology was obtained. Naphthalene, phenanthrene and pyrene were selected as models. It was found that the adsorption capacity of MGST showed the order of naphthalene (NAP) < phenanthrene (PHE) < pyrene (PYR).
