“…Modern water treatment methods involve advanced oxidation processes (AOPs) in which strong reactive oxygen species (ROS) are generated in situ to function as the active ingredient in oxidizing and degrading complex organic contaminants. The main active oxidant generated in all AOPs is the highly oxidizing hydroxyl radical, • OH, with a high reduction potential of 2.80 V E° (OH/H 2 O) = 2.80 V/SHE. − This approach has been proven to be highly effective in indiscriminately degrading organic contaminants and thus has gained much attention in recent years. As a result, AOPs, exemplified by the Fenton reaction in this study, have been subjects of intense studies as potential solutions to the wastewater remediation problem.…”

Explorations into the potential application of dualmetallic iron oxides, (FeXO 3 ), [where X is a transition metal] as heterogeneous electro-Fenton (HEF) catalysts have been of interest due to their enhanced catalytic activity. We thus present the synthesis and application of ilmenite (FeTiO 3 ) nanoparticles as a catalyst for HEF degradation of tetracycline (a pharmaceutical pollutant) in water. The ilmenite nanoparticles were characterized with electron microscopy, X-ray diffraction, Fourier transform IR spectroscopy, and BET analysis prior to their immobilization on a graphite felt (GF) cathode for HEF reactions. The effects of pH and catalyst loading on the HEF process were investigated. The extent of degradation was monitored with UV/vis spectroscopy and total organic carbon (TOC) measurements. The HEF system was robust over a wide pH range. Tetracycline in synthetic and real wastewater matrices was degraded, producing 61 and 40% TOC removal in 2 h, respectively. The comparative studies for the catalytic efficiencies of ilmenite (Ti-doped iron oxide) and commonly used HEF iron oxide catalysts, like magnetite, hematite, and goethite showed that synthetic ilmenite is an effective HEF catalyst for the degradation of organic pollutants in water. A slight Ti cocatalysis effect was observed in ilmenite nanoparticles based on the comparative HEF degradation results catalyzed by pristine iron oxide (hematite, Fe 2 O 3 ) and ilmenite (iron−titanium oxide). Our results show that ilmenite can be reused up to six cycles without loss of activity, and therefore it is an effective HEF catalyst for wastewater treatment.

Research has been conducted on the level of pollution caused by Leachate in shallow groundwater around Kebon Kongok landfill, Gerung, West Lombok. This research was conducted considering that water has many benefits in daily life, so it is important to know the quality of the water consumed. The research used experimental methods by analyzing physical parameters (Temperature, conductivity, pH and TDS) and chemical parameters in the form of heavy metal content (Pb, Fe, Cu and Mn). The results of physical parameter tests mostly show that the quality of shallow groundwater is still within the safe quality standard, there is 1 shallow groundwater point that is polluted due to the close proximity to the leachate. Chemical parameters indicate that the content of heavy metals is mostly well below the quality standard, except Cu metal is detected at 0.029 mg / l and Mn metal 1,457 mg / l at a distance of 50 m.KEYWORDS : Leachate; Shallow Water; Physics Parameters; Chemical Parameters

“…Leachate is known as an important source of environmental pollution, including groundwater, due to the presence of organic and inorganic substances, including heavy metals [ 13 ]. Landfill leachate contains many pollutants, including toxic substances and heavy metals, and usually has high COD [ 14 ]. Soil and water pollution in the areas near the landfill site and the areas affected by the landfill leachate is a serious concern in the management of municipal solid waste [ 15 ].…”
