The experimental adsorption equilibrium of Cd(II) onto chitosan (Cd(II)/CS) and methyl orange bentonite (MO/Bt) were studied in batch experiments at room temperature for an initial concentration 236.5 mg/L Cd (II) (pH = 5) 33 MO 3). rate increases rapidly t < 30 min, the is reached after this contact time both systems. values maximum amount adsorbed are qe 56.70 56.55 mg/g Cd/CS MO/Bt, respectively. obtained data analysed using linear nonlinear forms pseudo-first pseudo-second order kinetic...
Rosa damascena is referred to as the queen of roses due its ornamental, flavoring, and perfuming uses, along with recognized use in therapy. This study aimed investigate total phenols flavonoids contents, phenolic compounds, antioxidant antibacterial properties hydroethanolic extract from flowers, collected Middle Atlas Morocco (Khenifra). The were assessed using gallic acid quercetin standards, compounds characterized HPLC-PDA-ESI/MS. activity was evaluated by two methods, namely ferric...
Inorganic halide perovskites of the type AMX3, where A is an inorganic cation, M a metal and X anion, have attracted attention for optoelectronics applications due to their better optical electronic properties, stability, under moist elevated temperature environment. In this contribution, electronic, optical, thermoelectric, elastic properties cesium lead bromide, CsPbBr3, Rb-doped were evaluated using density functional theory (DFT). The generalized gradient approximation (GGA) in scheme...
Chitosan (CS) and nanocomposite 5%bentonite/chitosan (5%Bt/CS) prepared from the natural biopolymer CS were tested to remove Cu(II) ions using a batch adsorption experiment at various temperatures (25, 35 45°C). X-ray diffraction, Fourier transform infrared spectroscopy, thermogravimetric analysis/differential thermal analysis (TGA/DTA) used in characterisation. This confirmed exfoliation of bentonite (Bt) form nanocomposite. The kinetics copper on both solids was found follow...
Origanum compactum belonging to the family Lamiaceae is widely used in food and pharmaceutical fields due its biologically active substances. We aimed investigate total phenol flavonoid contents phenolic composition, evaluate antioxidant antibacterial properties of hydroethanolic extract from compactum. Total were evaluated using gallic acid quercetin as standards, respectively, profile was characterized high-performance liquid chromatography coupled a photodiode array electrospray...
A raw Moroccan clay locally named "Ghassoul" (Gh) was characterized using several techniques such as Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), Brunauer, Emmett and Teller method (BET), Scanning Electron Microscopy (SEM) simultaneous Thermo-Gravimetric Differential Thermal Analysis (TGA/DTA). These indicate that the Gh consists essentially of steveniste, calcite, dolomite quartz. The study interfacial electrochemical properties in different solutions electrolyte...
In this work, polyphenols were extracted from Anacylus clavatus flowers using a hydroethanolic solvent, and the obtained extract was studied for its total phenol flavonoid contents evaluated antioxidant antibacterial capacities. The of phenols flavonoids measured by employing gallic acid quercetin as references, respectively, phenolic composition analysis conducted high-performance liquid chromatography combined with photodiode array electrospray ionization mass spectrometry...
Adsorption of ortho-nitrophenol (o-NP) and para-nitrophenol (p-NP) from single binary aqueous solutions onto Al2O3 its composite, hexadecyltrimethylammonium bromide (HDTMA+/Al2O3), were studied in batch experiments at T = 25 °C pH 6. In order to overcome the problem overlapping absorbance bands o-NP p-NP, a first-order derivative UV/Visible spectrophotometric method (FODS) was applied for simultaneous determination each adsorbate their residual solutions. Experimental adsorption data p-NP...
Removal of para-nitrophenol (p-NP) from an aqueous solution was studied under various batch adsorption experiments, using alumina (Al2O3) and its composite hexadecyltrimethylammonium bromide (HDTMA+-Br-) as adsorbents. These were later characterized, before after p-NP, by thermal analysis (DSC-TG), X-ray diffraction (XRD), Fourier transform infrared (FTIR), UV/Visible spectroscopies. The results show that HDTMA+/Al2O3 adsorbents have a greater affinity toward p-NP than Al2O3 alone. Linear...
We have synthesized the organic-inorganic hybrid material [NH3-(CH2)6-NH3]MnCl4 (2C6MnCl4) by slow evaporation method at room temperature.
