The function of NLRP3 within lead-induced neuroinflammation and also feasible main system.
The pseudo-second-order model was in good fitting with kinetics results. The adsorption isotherm results showed that CZA exhibits better adsorption capacity for As(III) than CCA and the Langmuir isotherm model described the data well for both nanocomposites. Thermodynamic studies illustrated the endothermic nature of CCA and exothermic nature on CZA, as well as the fact that the adsorption process is spontaneous. A real water sample collected from well located in Gabes (Tunisia), has also been treated. The obtained experimental results were confirmed that these sorbents are efficient for the treatment of hazardous toxic species such as. V.CuSO4/TiO2 catalysts with high catalytic activity and excellent resistant to SO2 and H2O, were thought to be promising catalysts used in Selective catalytic reduction of nitrogen oxides by NH3. The performance of catalysts is largely affected by calcination temperature. Here, effects of calcination temperature on physicochemical property and catalytic activity of CuSO4/TiO2 catalysts were investigated in depth. Catalyst samples calcined at different temperatures were prepared first and then physicochemical properties of the catalyst were characterized by N2 adsorption-desorption, X-ray diffraction, thermogravimetric analysis, Raman spectra, Fourier-transform infrared spectroscopy, X-ray photoelectron spectroscopy, temperature-programmed desorption of NH3, temperature-programmed reduction of H2 and in situ diffuse reflectance infrared Fourier transform spectroscopy. Results revealed that high calcination temperature had three main effects on the catalyst. First, sintering and anatase transform into rutile with increase of calcination temperature, causing a decrement of specific surface area. Second, decomposition of CuSO4 under higher calcination temperature, resulting in disappears of Brønsted acid sites (S-OH), which had an adverse effect on surface acidity. Third, CuO from the decomposition of CuSO4 changed surface reducibility of the catalyst and favored the process of NH3 oxidation to nitrogen oxides (NOx). Thus, catalytic activity of the catalyst calcined under high temperatures (≥600°C) decreased largely. V.Nowadays, widespread researches have been focused on the development of effective photocatalysts to remove pollutants of the aquatic system. In accordance with the universal studies, two new sets of UiO-66@ metal oxide (including ZnO and TiO2)/graphene oxide heterojunctions were synthesized for photodegradation of aromatic (tetracycline) and nonaromatic (malathion) pollutants which are challenging cases in the environment. The dosage of the photocatalyst, pH of the solution, the type of metal oxide, and the presence of various scavengers are assayed parameters in this work. In the optimum condition, maximum photodegradation efficiency is achieved in 90 min for tetracycline (81%) and malathion (100%) by the UiO-66@ZnO/graphene oxide. The superior separation of charge carriers by Z-scheme mechanism, excellent electron mobility on layers of graphene oxide and high surface area are factors that enhanced the efficiency. Furthermore, in comparison with pure UiO-66, the band gaps belong to heterojunctions revealed a red shift in the absorption edge, which can be responsible for more expand adsorption of the solar spectrum. Total organic carbon analysis verified the decontamination of these pollutants in the solution. The produced main intermediates during the photocatalytic process were identified and the possible degradation pathway proposed. In general, the superior photocatalytic activity suggests that these designed photocatalysts can be a promising choice for having a clean future. V.Because of its significant toxicological effects on the environment and human health, arsenic (As) is a major global issue. In this study, an Fe-based metal-organic framework (MOF) (Materials of Institut Lavoisier MIL-100 (Fe)) which was impregnated with reduced graphene oxide (rGO) by using a simple hydrothermal method and coated with birnessite-type manganese oxide (δ-MnO2) using the one-pot reaction process (MIL-100(Fe)/rGO/δ-MnO2 nanocomposites) was synthesized and applied successfully in As removal. The removal efficiency was rapid, the equilibrium was achieved in 40 min and 120 min for As(III) and As(V), respectively, at a level of 5 mg/L. The maximum adsorption capacities of As(III) and As(V) at pH 2 were 192.67 mg/g and 162.07 mg/g, respectively. The adsorbent revealed high stability in pH range 2-9 and saturated adsorbent can be fully regenerated at least five runs. IRAK-1-4 Inhibitor I The adsorption process can be described by the pseudo-second-order kinetic model and Langmuir monolayer adsorption. The adsorption mechanisms consisted of electrostatic interaction, oxidation and inner sphere surface complexation. V.The aluminum ions generated from mining aluminum, electrolytic aluminum and the industrial production of aluminum-based coagulants (such as AlCl3 and Al2(SO4)3) enter sewage treatment plants and interact with activated sludges. An anaerobic/anoxic/oxic (A2O) process was used to reveal the effects of Al3+ on the pollutant removal efficiencies, bioflocculation and the microstructure of sludge. The results showed that a low concentration of Al3+ improved the pollutant removal efficiencies and increased the sludge particle size. However, a high concentration of Al3+ hindered microbial flocculation and reduced the pollutant removal efficiencies. With a 10 mg/L Al3+ addition, the chemical oxygen demand (COD), total nitrogen (TN) and NH4+-N increased by 3%, 16% and 27%, and reached as high as 68%, 60% and 87%, respectively. At the same time, the dehydrogenase activity, flocculation ability (FA) and contact angle of the sludge reached their maximum levels at 41.3 mg/L/hr, 45% and 79.63°, respectively. The specific surface area of the sludge decreased to 7.084 m2/g and the sludge pore size distribution shifted to concentrate in the mesoporous range. Most of Al3+ was adsorbed on the surface of sludge, changing the physicochemical properties and physical structure of the sludge. V.This research aimed to evaluate the alga Scenedesmus obliquus toxicity induced by textile-dyeing effluents (TDE). The toxicity indicator of TDE in alga at the physiological (algal growth), biochemical (chlorophyll-a (Chl-a) synthesis and superoxide dismutase (SOD) activity) and structural (cell membrane integrity) level were investigated. Then we further study the relationship among toxicity indicators at physiological and biochemical level, and supplemented by research on algal biomacromolecules. According to the analysis of various endpoints of the alga, the general sensitivity sequence of toxicity endpoints of Scenedesmus obliquus was SOD activity > Chl-a synthesis > algal growth. The stimulation rate of SOD activity increased from day 3 (57.25%~83.02%) to day 6 (57.25%~103.81%), and then decreased on day 15 (-4.23%~-32.96%), which indicated that the antioxidant balance system of the algal cells was destroyed. The rate of Chl-a synthesis inhibition increased gradually, reaching 19.70%~79.39% on day 15, while the rate of growth inhibition increased from day 3 (-12.
