In this research, a novel magnetic hydrogel (MHG) adsorbent based on Fe3O4/poly(2-hydroxyethylmethacrylate-co-2-acrylamido-2-methylpropanesulfonic acid) Fe3O4/poly(HEMA-co-AMPS) was synthesized by in situ co-precipitation of Fe3O4 particles inside poly(HEMA-co-AMPS) hydrogels. This used to adsorb the organic cationic dye methylene blue (MB) from aqueous solutions. The properties were characterized FT-IR, TGA, XRD, VSM, and EDX-SEM techniques. degree swelling recorded water, acidic medium...
Abstract Wastewater containing dyes is considered as the top-priority pollutant when discharged into environment. Herein, we report for applicability of 254 nm ultraviolet light and electrochemical process using a titanium ruthenium oxide anode degradation Allura red erythrosine dyes. During photolytic process, 95% dye (50 ppm) was removed after 1 h at pH 12 35 °C, whereas 90% color removal achieved 6 treatment 6.0 30 °C. On other hand, 99.60% (200 within 5 min by applying current density (5...
Curcumin is the main colorant of curcuma longa plant, a food with many benefits for human health. This work aims to synthesize novel molecularly imprinted polymer (MIP) selective detection curcumin in real samples obtained from local market Peru. MIPs were synthesized via bulk polymerization using curcumin, acrylamide, ethylene glycol dimethacrylate, ABCV, and acetonitrile. FTIR spectra showed equal MIP NIP. N2 physisorption analysis presented higher value BET surface (28.5 m2 g−1) compared...
A novel and greener ultrasonically assisted/modified cloud point extraction procedure for the simultaneous preconcentration of lead cadmium in serum samples different types gallstone patients was developed. The chelates under study metals, formerly formed with 8-hydroxyquinoline, were extracted micelles a nonionic surfactant prior to analysis by flame atomic absorption spectrometer (FAAS). After arrival point, critical micellar mass produced homogenously dispersed aqueous phase help...
Abstract This study investigated the effect of ethanolic sesame cake extract on oxidative stabilization olein based butter. Fractionation cream was performed by dry fractionation technique at 10 °C, (SCE) incorporated into butter three different concentrations; 50, 100, 150 ppm (T 1 , T 2 3 ) and compared with a control. The total phenolic content SCE 1.72 (mg gallic acid equivalent g −1 weight). HPLC characterization revealed presence antioxidant substances viz. sesamol, sesamin sesamolin...
This work describes an electrochemical sensor for the selective recognition and quantification of amoxicillin a β-lactam antibiotic in real samples. consists carbon paste electrode (CPE) modified with mag-MIP (magnetic molecularly imprinted polymer), which was prepared by precipitation method via free radical using acrylamide (AAm) as functional monomer, N,N′-methylene bis (MBAA) crosslinker, potassium persulfate (KPS) initiator, to functionalized magnetic nanoparticles. The non-imprinted...
Magnetic molecularly imprinted polymers (MMIPs) contain the predesigned specialized recognition capability that can be chosen to build credible functional materials, are easy handle and have a good degree of specificity. Hence, given piece work is intended design novel electrochemical sensor incorporating magnetite-based polymers. The building materials consisted cross-linker (EGDMA), reaction-initiator (AIBN), monomer (methylene succinic acid-MSA), template molecule (Sunset Yellow-SY dye)....
A chitosan magnetic membrane was prepared in order to confer properties the membrane, which could be used for removal of cations from aqueous solution. The crosslinked compared with pristine term stability, morphology and cation adsorption capacity. fabricated materials are thermally stable as shown by thermogravimetric curves. containing nickel particles (CHNiF-G) shows high thermal stability other membranes. Fourier transform infrared spectroscopy showed successful preparation membrane....
Abstract Adsorption of dibenzothiophene (DBT) from model oil was investigated using composites pure activated charcoal and bentonite clay. DBT adsorption carried out in batch mode experiments at laboratory scale, where the developed composite materials showed a synergistic effect removal terms improved surface acidity mesoporous structure Thermodynamics, kinetics, optimization various parameters were investigated. Kinetic analyses proved that followed pseudo‐second‐order kinetics. To study...
