The present work is focused on the degradation of 4-chloro-2-nitrophenol in aqueous solution containing nano titanium dioxide, hydrogen peroxide and the combination of nano-TiO2/H2O2. The effect of experimental parameters, such as the amount of nano- TiO2 concentration of H2O2, initial concentration of 4-chloro-...

Titanium dioxide (TiO2) and Fe3O4 magnetite particles were coated on spherical Kissirises; glucose oxidase (GOx) enzyme was immobilized on Kissiris/Fe3O4/TiO2 by physical adsorption. This catalyst was analyzed by a scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and energy dispersive X-ray (EDX) measurements. The performance of the prepared biocatalyst in the...

Pectoralis muscle quality was evaluated from 18-wk-old tom turkeys after electrical stun, carbon dioxide stun, or no stun methods were applied. Color was measured on raw muscle and cooked meat using a colorimeter. Muscle pH was measured 15 min post-mortem (initial), 24 h post-mortem (final), and after cooking. The right Pectoralis muscle of each carcass was excised for m-calpain analysis within...

The influence of lipid composition, internal pH and internal buffering capacity on the retention properties of vincristine loaded into large unilamellar vesicle (LUV) systems in response to transmembrane pH gradients has been assessed. It is shown that increasing the (saturated) acyl chain length of the phosphatidylcholine molecule, increasing the internal buffering capacity, and decreasing the...

Textile wastewater contains a number of dyes which are known to be toxic and carcinogenic. In this study the results show that the Fenton (Fe2+/H2O2) process is an efficient method for the removal of Acid Brown 14 (A.BR14) and Cationic Blue 41 (C.B41) dyes from textile wastewater. In this method, two reagents Fe2+and H2O2 are used and do not require any additional energy. Several experiment...

The aim of this study is to investigate the nitrate adsorption on granular ferric hydroxide (GFH). The effect of factors such as initial concentration of nitrate, pH, contact time, and adsorbent mass were determined. The study was done in laboratory–scale in which synthetic nitrate solutions in a batch reactor were placed in contact with the adsorbent to model adsorption kinetics. It was found ...

Contamination of water resources with toxic elements is one of the challenges of thetoday's world. In this research, application of Goethite nanoparticles in removingcontamination of arsenic and mercury from synthetic wastewater in a batch mode isinvestigated. For this purpose, the effect of different factors including pH, adsorbent dosage,contac...

In the present work, the effect of initial pH of methylene blue solution on the kinetics of dye sorption from synthetic aqueous solution by a natural waste material namely: orange peels, was studied. Kinetic data were measured in batch conditions. Methylene blue uptake was time contact and solution initial pH dependent. Maximum dye sorption was found to occur at initial pH 9. Two simplified kin...
