BACKGROUND For thousands of years, Tunisian geothermal water has been used in bathing. Indeed, thermal baths "Hammam" were recommended in the treatment of different type of illnesses as, for instance, for relaxing joints and soothing. The ability of microalgae to sustain at the high temperature makes them potential producers of high value thermostable bio-products. This study aimed to explore t...

In this study, degradation of p-chlorophenol (p-CP) was evaluated using persulfate (PS) activated zerovalent iron (ZVI) based ultraviolet (UV) in a bench scale photoreactor. The effect of operational parameters such as solution pH (3, 7, and 11), reaction time (0-60 minutes), ZVI dosage (0.15, 1.25, 0.5, 1, and 1.5 mM), PS concentration (0.5, 1.5, 2, 2.5, 3, and 4 mM), and initial p-CP concentr...

This paper uses a novel account of non-ideal political action that can justify radical responses to severe climate injustice, including and especially deliberate attempts engineer the system in order reflect sunlight into space cooling planet. In particular, it discusses question what those suffering from injustice may do secure their fundamental rights interests face change impacts. Using exam...

Abstract. In-cloud chemistry has important ramifications for atmospheric particulate matter formation and gas-phase chemistry. Recent work shown that, like hydrogen peroxide (H2O2), the two main isomers of isoprene hydroxyl hydroperoxide (ISOPOOH) oxidize sulfur dioxide dissolved in cloud droplets (SO2,aq) to sulfate. The revealed that pathway SO2,aq oxidation with ISOPOOH differs from H2O2. We...

Abstract. The co-polluted days by ozone (O3) and PM2.5 (particulate matter with an aerodynamic equivalent diameter of 2.5 µm or less) (O3–PM2.5PDs) were frequently observed in the Beijing–Tianjin–Hebei (BTH) region warm seasons (April–October) 2013–2020. We applied 3-D global chemical transport model (GEOS-Chem) to investigate physical characteristics O3–PM2.5PDs composited analyses such that c...

Wastewaters from the olive oil industry are a regional environmental problem. Their phenolic content provides inherent toxicity, which reduces treatment potential of conventional biological systems. In this study, Sulfate Radical based Advanced Oxidation Processes (SRbAOPs) compared with advanced oxidation processes (namely Fenton’s peroxidation) as depuration alternative. Synthetic mill wastew...

Abstract In this study, zero-valent iron (ZVI) is applied to activate persulfate (PDS) for the degradation of amaranth (AMR). The effects PDS concentration, ZVI solution pH , temperature, and reaction time on AMR by ZVI/PDS advance oxidation process are investigated. Sulfate hydroxyl radicals involved in main pathway sulfate radical acts as a dominant oxidant. CCD (central composite design) pla...
