A magnetic carbon-coated Fe-C/N composite was synthesized by a simple impregnation method and its performance in activating persulfate (PS) to degrade Acid Red 73 (AR 73) was investigated. The as-prepared carbon-coated Fe-C/N hybrid material was characterized via transmission electron microscopy...

This study introduces a new and bio-friendly adsorbent based on natural and cetyltrimethylammonium bromide (CTAB) modified adsorbent, celery (Apium graveolens) residue for removal of organic pollutants. The adsorbent was characterized by Fourier transform infrared (FTIR) spectroscopy, scanning e...

Hypochloric acid (HClO) is mainly distributed in acidic lysosomes of phagocytes and closely associated with numerous physiological and pathological processes, especially inflammatory response. Fluorescent probe has become an important tool for imaging HClO in lysosomes, but suffered from interfe...

Equilibrium, kinetics and thermodynamic studies on the removal of Acid Red 57 (AR57) by biosorption onto dried Cephalosporium aphidicola (C. aphidicola) cells have been investigated in a batch system with respect to pH, contact time and temperature. The results showed that the equilibrium time w...

The adsorption of Acid Red 57 (AR57) onto calcined-alunite was examined in aqueous solution in a batch system with respect to contact time, pH and temperature. The first-order, pseudo-second-order kinetic and the intraparticle diffusion models were used to describe the kinetic data and the rate ...

Filtration performances of membranes could be improved by blending with organic/inorganic additives or by treating plasma and radiation induced grafting techniques. In this study, acrylic acid (AA) was applied to surface of the polyvinylidene fluoride (PVDF) membrane by chemical grafting method ...

Solubility of C.I. Acid Red 57 (AR57) in supercritical carbon dioxide was measured by ion-pairing with hexadecyltrimethylammonium (HDTMA) bromide. The solubility measurements of AR57 and AR57-HDTMA in supercritical carbon dioxide without/with methanol as a modifier solvent were carried out at th...

The adsorption of Acid Red 57 (AR57) onto surfactant-modified sepiolite was investigated in aqueous solution in a batch system with respect to contact time, pH and temperature. The surface modification of surfactant-modified sepiolite was controlled using the FTIR technique. The pseudo-first-ord...

Sepiolite, a highly porous mineral, is becoming widely used as an alternative material in areas where sorptive, catalytic and rheological applications are required. High ion exchange capacity and high surface area and more importantly its relatively cheap price make it an attractive adsorbent. I...

The adsorption of Acid Red 57 (AR57) onto Polyacrylonitrile/activated carbon (PAN/AC) composite was investigated in aqueous solution in a batch system with respect to contact time, pH and temperature. Physical characteristics of (PAN/AC) composite such as fourier transform infrared (FTIR) spectr...

A new metallorganic compound glyphosate ferrous with particle diameter about 150 nm was synthesized in this paper. Research results indicate that the compound has good catalytic properties on degradation of methyl orange (MO). There is about 99.48% of MO was degraded in 10 min when content of gl...

ObjectivesNon-alcoholic fatty liver disease (NAFLD) is one of the most common public health issues worldwide. Oranges are the most popular fruit consumed in the world. Admittedly, flavonoids in oranges act as antioxidants and improve liver steatosis. However, oranges also are rich in fructose, w...

An extensive study has been carried out where CO2 has been used both as solvent and antisolvent to appreciate orange leaves as a source of powerful antioxidant nanoparticles. In the former case, the leaves were processed directly to yield particles in the nano or micrometer range. In the latter ...

With the widespread application of synthetic pigments in the food industry, food safety incidents caused by illegal addition of pigments have become more frequent. In this study, we synthesized core–shell nanomaterials for use in sensitive, fast, convenient, nondestructive detection and having ...

New tools are desirable to examine the metabolic state of individual cells within tissues. We proposed a fluorescence-based procedure consisting of acridine orange staining and fast green counterstaining (AO-FG) to improve the selectivity of the former for nucleic acids (acridine orange stains b...

The availability of pure isomers of lactic acid is a key aspect of the fabrication of polymers based on poly-lactic acid with enhanced mechanical and thermal properties. The main problems presented in the fermentation process to d-Lactic acid production are the costs derived from the carbon and ...

The effectiveness of Rhodotorula mucilaginosa in combination with salicylic acid (SA) was explored for the control of green mold decay of oranges and the mechanisms involved. The results of the study showed that treatments with the diverse concentrations of SA was remarkable in reducing the dise...

The statistical Response Surface Methodology (RSM) is applied to investigate the effect of different parameters (current density, j, NaCl concentration, [NaCl], pH, and temperature, θ) and their interactions on the electrochemical degradation of the Acid Green (AG) 28 dye using a Ti/β-PbO2 or ...

In this work, a comprehensive comparative analysis of various approaches for the modeling of the adsorption process was carried out to understand the adsorption isotherm and kinetics. The evaluated isotherm models included Langmuir, Freundlich, Dubinin–Radushkevich, Tempkin, Flory–Huggins, Hil...

Proteolysis in Danish blue cheese was studied during 9 weeks’ ripening. Levels of pH 4.6-soluble N as a percentage of total N increased from 7.2% to 25%, indicating extensive proteolysis. Urea-polyacrylamide gel electrophoretograms confirmed the extent of proteolysis through chymosin and plasmi...
