This paper aims to assess soil fertility and risk contamination parameters in response increased amendment rates of sewage sludge application, under semi-arid climatic conditions Morocco, using two textures: A (clay-silty) B (sandy-clay) over years. To this end, soils treatments physicochemical parameters, heavy metals content, degree pollution associated risks were evaluated compared controlled soils. The results showed that all studied changed significantly (p < 0.05) a dose-dependent...
Since December 2019, the coronavirus disease (COVID-19) pandemic has catapulted world into a marked health crisis, with over 29 million cases and >930,000 deaths. To better detect affected individuals at an early stage stop progression to advanced stage, several studies have been conducted identify clinical, biological, radiological characteristics of COVID-19. This study aimed enrich literature by critically analyzing clinical biological 134 patients from North African Mediterranean...
Biodiesel is a potential alternative for fossil fuel. However, its large-scale application held up by the disadvantage of homogenous process, scarce availability raw materials and production cost, which higher than diesel. In this work, biodiesel was carried out using both refined used cooking oils. The process investigated in batch reactor, presence CaO as heterogeneous catalyst prepared calcination natural Waste Grooved Razor Shell (GRS). Characterizations X-Ray Diffraction (XRD) Thermal...
BACKGROUND The present work explores the catalytic and electric performance of a microbial fuel cell (MFC) implemented with high chemical oxygen demand (COD) industrial wastewater from Spain. polymer inclusion membrane based on 70% [MTOA][Cl] IL was used as separator showed good efficiency in power production COD removal. RESULTS Outputs 72% conversion, 200 mV voltage 32 mW m−3 density were obtained, demonstrating that slaughterhouse is feedstock for scale-up this technology. Furthermore,...
A reusable heterogeneous catalyst was obtained from eggshell by a simple heat treatment method. Calcined used in the transesterification of vegetable oil with methanol to produce biodiesel. To explain effect calcination temperature, we investigated process thermal gravity analysis (TGA), X-ray diffraction (XRD) pattern, Fourier transform infrared spectroscopy (FT-IR), atomic emission spectrometry (ICP-AES), and scanning electron microscopy (SEM). The yield biodiesel affected reaction...
Abstract Microbial fuel cells (MFCs) have attracted a great deal of attention as promising technology for recovering electricity from organic substances by harnessing the metabolic activities microorganisms. The objective this study is to assess efficacy LiTa 0.5 Nb O 3 /g-C N 4 (LTN/g-C ) heterojunction photocathode catalyst within single-chamber microbial cell operating under both light irradiation and dark conditions. X-Ray diffraction (XRD), Fourier transform infrared spectroscopy...
Microbial fuel cells (MFCs) are an environmentally friendly technology that can recover electricity directly from several wastes at ambient temperatures. This work explores the use of mineral oil refinery wastewater as feedstock in single-chamber air-cathode MFC devices. A polymer inclusion membrane based on ionic liquid methyltrioctylammonium chloride, [MTOA+][Cl−], a concentration 70% w/w, was used separator, showing good efficiency power production and chemical oxygen demand (COD)...
The purpose of this study is to evaluate the metal (As, Cd, Pb, Zn and Cu) pollution surface water in a mining environment. To achieve this, samples were taken from Moulouya River, Ansegmir tributary Hassan II Dam located downstream abandoned Pb mine. Which allowed conduct comprehensive physicochemical analysis. results showed high concentrations most sites. In fact, levels arsenic, cadmium, copper lead are much higher than specific values set by World Health Organization for drinking water....
Microbial fuel cells (MFCs) are a promising technology that can be applied in bifunctional process which wastewater treatment is used for renewable electric power generation. In this study, novel transition metal-modified Keggin-type lacunar polyoxometalate salts (L-POMs) Cs5PMo11M(H2O)O39 (M = Fe, Co), were synthesized and characterized by X-ray diffraction, SEM, EDX, IR, TGA/DSC, UV-Vis/DSR spectroscopies to tested, the first time, as cathode component wastewater-fed air chamber MFCs. Both...
Toxic contamination of agricultural soils by trace metal(oid)s can pose detrimental effects on human health and agroecological systems. In this view, the current research explored total available in surface assessed associated hazards using pollution indices, PMF modeling, PCA, Montecarlo probabilistic risk assessment with 10,000 repetitions. The mean concentrations Cd, Pb, As, Cr, Ni, Cu, Zn, Fe were 0.89, 24.86, 1.81, 19.10, 25.44, 7.98, 49.12 6183.32 mg kg−1 dry weight, respectively....
In this paper, several physical and chemical analyses have been performed to determine the composition of dust naturally deposited on photovoltaic panels installed in our RDI Solar Energy Platform Rabat. The mineralogical was determined by X-Ray Diffraction (XRD) Fluorescence Analysis (XF). Additional characterization has also Thermal Infrared Spectroscopy (IR). XF results show that silica, alumina, iron oxide, calcium magnesium oxide potassium are most abundant elements dust. Mineralogical...

MFC is a promising technology that can be used for simultaneous electricity generation and wastewater treatment. Power energy of ferroelectric cathodic ceramic, Li0.95Ta0.76Nb0.19Mg0.15O3 (LTNMg), has been measured in microbial fuel cells, integrating single chamber fed by industrial (CODinitial = 471 mg L−1, pHinitial 7.24 at T 27 °C). In this process, the mixed multicomponent oxide material prepared characterized XRD, PSD, TEM, UV-Vis spectroscopy. The catalytic activity investigated COD...
