“…The initial COD of 15 mg/L 4-NP was measured to be 37 mg/L. Due to the interference of persulfate for COD measurements and the overestimation, the corrected values were determined 33 . The COD of the reaction mixture without 4-NP (0.003 g catalyst, 0.015 g sodium peroxydisulfate, 10 mL water) as the blank sample was obtained to be 122 mg/L.…”

The replacement of metals in catalytic processes is highly demanded to improve sustainability and economic growth. Poor stability and metal leaching are the main drawbacks of metal-based catalytic reactions. This work represented the use of nitrogen and sulfur-co-doped mesoporous carbon material ((N, S)-MPC) as a metal-free catalyst for the degradation of 4-nitrophenol (4-NP) as a priority pollutant announced by the Environmental Protection Agency through the persulfate-based advanced oxidation process. A low amount of (N, S)-MPC catalyst (0.3 g/L) exhibited superior performance for the degradation of 4-NP within 3 h at room temperature and unadjusted pH. The COD removal was calculated to be 76% using (N, S)-MPC catalyst. Interestingly, the degradations kinetics of 4-NP followed the zero-order kinetics with the rate constant of 0.505 min−1. The radical quenching experiment was accomplished to investigate the activation pathway of degradation. A real sample from an oil and gas company was treated with the (N, S)-MPC catalyst, which showed excellent total decontamination of 61%. The recyclability and stability of the catalyst have been evaluated for three runs. Owing to the obvious benefits such as high efficiency, metal-free nature, and recyclability, the presented catalyst can improve pollutant removal from aqueous media and practical environmental remediation.

“…Notably, the degradation rate of TC reached 97.2% in 60 min under visible light irradiation (λ > 400 nm) with NiFe 2 O 4 /C. Qin et al [131] [132] found that pyrite from mine waste was an excellent mineral catalyst and •OH was the main oxidizing species in a heterogeneous Fenton-like pyrite/H 2 O 2 process. More than 85% of TC was removed in 60 min.…”

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.

In this study, it was aimed to remove COD from wastewater prepared from a mixture of rhodamine 6G, methyl orange, and crystal violet dyes using natural pyrite ore as a heterogeneous fenton catalyst. The parameters of pH (2-9), H2O2 concentration (0.5-5 g/L), and catalyst dosage (0.5-5 g/L), which are thought to have major effects on the heterogeneous fenton process in COD removal, were investigated in a batch system. Characterization studies of natural pyrite ore were performed by X-Ray Diffractometer (XRD), Scanning Electron Microscope (SEM), Energy Dispersive X-Ray Spectroscopy (EDX), and Fourier Transform Infrared Spectroscopy (FTIR) spectroscopy analyses. According to the data obtained, optimum values were determined as pH of 2, H2O2 concentration of 2 g/L, and 1.5 g/L of catalyst dosage. The COD removal efficiency was calculated as 94.7% under optimum conditions. According to the characterization results, it was determined that the pyrite ore contains (wt. %) Fe (44.87%) and S (51.02%) in a major proportion. The pyrite ore had a well crystalline and irregular structure. The fingerprint bands such as Fe-O, Fe-S are determined by FTIR spectrum. Pyrite was found as an effective catalyst for COD removal in this study and can be used as a promising catalyst in future heterogeneous fenton studies by expanding its catalyst property.
