“…As the degradation via OH radicals produced in the solution phase (mechanism (ii)) is inevitable and has well been established in the pyrite-Fenton process by many researchers (Che et al, 2011;Kantar et al, 2015aKantar et al, , 2015bKantar et al, , 2019aKantar et al, , 2019bKantar et al, , 2019cOral et al, 2017;Oral and Kantar, 2019;Rahim Pouran et al, 2014;Shaida et al, 2018), additional experimental runs to prove the incidence of this reaction doesn't seem necessary. Moreover, the total concentration of Fe in the treated TTC solution at present work was measured and detected to be about 0.43 mg/L, which confirmed the occurrence of the pyrite-Fenton reaction to produce solution phase OH radicals.…”

Degradation of tetracycline (TTC) with a heterogeneous Fenton-like pyrite/H 2 O 2 process by pyrite from mine waste as a mineral catalyst was investigated. The study focused on identifying the main oxidizing agents and degradation mechanisms along with operational variables including solution pH, pyrite and H 2 O 2 concentration, contact time, solution temperature, and initial TTC concentration. Catalyst characterization tests revealed that pyrite is a mesoporous powder with a high degree of FeS 2 purity. Radical scavenger tests demonstrated that OH was the main oxidizing agent generated by both solution and surface phase reactions. During the pyrite/H 2 O 2 process, more than 85% of TTC was mineralized in 60 min and the maximum TTC removal was attained in the solution at an acidic pH value (4.1). The most abundant transformation products of TTC, formed by the attack of OH radicals, were simple chain carboxylic acids. Cultured cells of human embryonic kidney (HEK) were used for the cytotoxicity assessment of raw and pyrite/H 2 O 2 treated TTC solutions. The results illustrated that the viability of HEK cells was enhanced considerably after treating TTC solutions under optimal conditions. Accordingly, pyrite originating from mine waste is a practically effective and cost-effective catalyst in heterogeneous Fenton-like systems for mineralization and degradation of emerging contaminants such as antibiotics.

“…The pH did not influence the removal rate very much. Kantar, Oral, and Oz (2019) utilized Fenton process to treat pharmaceutical wastewater with citrate as the complexing agent and pyrite as the catalyst. The process was dependent on Fe dissolution from pyrite, and the Fe dissolution process generated • OH in the system.…”

By summarizing 187 relevant research articles published in 2019, the review is focused on the research progress of physicochemical processes for wastewater treatment. This review divides into two sections, physical processes and chemical processes. The physical processes section includes three subsections , that is, adsorption, granular filtration, and dissolved air flotation, whereas the chemical processes section has five subsections , that is, coagulation/flocculation, advanced oxidation processes, electrochemical, capacitive deionization, and ion exchange.

“…Therefore, due to the low-cost and environmental friendly characteristics, waste-derived pyrite can be considered as a catalyst for water and wastewater treatment. Many researchers have confirmed the cost-effectiveness of pyrite as a catalyst for the removal of water pollutants [33,34]. Moreover, pyrite is stable and has a low solubility in water.…”
