Abstract Alginate-SBA-15 (ALG-SBA-15) was synthesized by encapsulation of the nanoporous SBA-15 in biopolymeric matrix calcium alginate. This adsorbent characterized using powder X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), nitrogen adsorption-desorption and Fourier transform infrared (FT-IR) spectroscopy. Tests were then conducted to study adsorption lead ions onto ALG-SBA-15 from an aqueous solution for effect pH, contact time temperature batch systems. Freundlich Langmuir...
Bacterial meningitis, an infection of the membranes (meninges) and cerebrospinal fluid (CSF) surrounding brain spinal cord, is one major causes death disability worldwide. Higher case-fatality rates short survival times have been reported in developing countries. Hence, a quick, straightforward, low-cost approach great demand for diagnosis meningitis. In this research, microfluidic fully paper-based analytical device (μFPAD) integrated with loop-mediated isothermal amplification (LAMP)...
Abstract A low‐cost microfluidic platform integrated with a flexible heater was developed for in situ temperature‐dependent spectroscopic measurement at the point of care. After verifying system by comparing on‐chip methylene blue conventional spectroscopy, we demonstrated its applications absorption spectroscopy model biomolecule, curcumin. The is portable, battery‐powered and requires ultra‐low volumes analytes, which highly suitable point‐of‐care characterization.
Ultrasound assisted emulsification of solidified floating organic drop microextraction (USAE-SFODME), combined with electrothermal atomic absorption spectrometry (ETAAS), was developed for the preconcentration and determination trace amounts As(III) As(V) in environmental water samples. At pH = 1, formed complexes ammonium pyrrolidine dithiocarbamate (APDC) these were extracted into fine droplets 1-dodecanol (extraction solvent) which dispersed aid ultrasonication sample solution. After...
Separation of CO2 from air was simulated in this work. The considered process for removal a hollow-fiber membrane contactor and an aqueous solution 2-amino-2-metyl-1-propanol (AMP) as absorbent. model developed based on mass transfer well chemical reaction solvent the contactor. equations were solved using finite element method. Simulation results compared with experimental data, good agreement observed. revealed that increasing velocity enhances Moreover, it found counter-current mode is...
Abstract In this work, readily prepared copper supported on the SiO 2 nanoparticles has been found to effectively catalyze 1,3‐dipolar cycloaddition of a variety azides, alkynes, epoxides and sodium azide, furnishing corresponding 1,2,3‐triazoles β ‐hydroxytriazoles. Click reaction proceeds in short times under mild conditions, resulting products are obtained good yields at ambient temperature.
Mesoporous MCM-41 has been modified by loading of zinc hexacyanoferrate (ZnHCF) as a new adsorbent for cesium. The ZnHCF-loaded mesoporous (ZnHCF-MCM-41) was characterized using powder X-ray diffraction and nitrogen adsorption–desorption isotherm data, fourier transform infrared spectroscopy, scanning electron microscopy coupled with energy dispersive X-ray. cesium removal performance ZnHCF-MCM-41 from aqueous solutions studied, the effect various parameters, such initial pH value solution,...
This article presents an overview of the Jerusalem artichoke and its potential uses in consumer food products. artichoke, native to North America, is characterized by sunflower-like appearance carbohydrate-rich tubers. For centuries, tubers were a source for Aboriginal Canadians early European settlers. Today, used obtain inulin addition into Inulin polysaccharide that provides several health benefits when consumed. Due unique structure fructose glucose molecules, indigestible human...
USAL-SPE-LDS-DLLME has been applied for the determination of OPPs in soil samples.
In this study, mesoporous MCM-41 has been modified by supporting of lead hexacyanoferrate (PbHCF) as a new adsorbent for strontium. The hexacyanoferrate-loaded (PbHCF-MCM-41) was characterized using powder X-ray diffraction (XRD) and nitrogen adsorption-desorption isotherm data, infrared spectroscopy, scanning electron microscopy coupled with energy dispersive (SEM-EDX) its strontium adsorption performance in aqueous solution investigated. effect the various parameters like contact time,...
