Hydrogen peroxide as an oxidant agent was used for desulfurization of a petroleum hydrocarbon fraction (C10-C22) with boiling range of 175-375 ℃, (light fuel oil) in the presence of acetic acid as catalyst. The oxidation was performed in an ultrasonic bath. It is found that increasing the amount of hydrogen peroxide lead to increase the oxidation rate and so desulfurizatio...

Here we demonstrate a simple, nondestructive method for the preparation of stable aqueous colloidal solutions of graphene nanoribbons and carbon nanotubes. The method includes sonication of carbon nanomaterials in hypophosphorous acid, filtration accompanied by washing the solids with water and dispersion of the solids in a fresh portion of water to form colloidal solutions.

The aim of this study was to treat wastewater from washing, cutting or crushing intermediate bulk containers (IBCs), steel drums and plastic drums, using the sulfate radical-based oxidation method. In study, it planned make suitable for activated sludge treatment by applying neutralization after a process. Samples were taken industry three times these processes. To determine optimum conditions ...

Acid-soluble collagen (ASC) is generally extracted by acid solubilization, followed precipitation and dialysis. Such a process typically time consuming tedious, especially for A simplified recovery based on water washing/centrifugation of pellets to replace dialysis was successfully developed. An ASC pellet from salmon (Oncorhynchus nerka) skin obtained salt (2.6 M). The washed with 50 volumes ...

Abstract Simultaneous reduction in activity of fat destabilizing enzymes (lipase and lipoxygenase), contaminants heavy metals (As, Cd, Pb, Hg), antinutrient phytic acid hazardous coliforms rice bran was investigated. Application washing, soaking the washed sample at different pH values (2, 6 9) alone or combination with ultrasonication were examined. While washing beneficial, its low efficiency...

The study was conducted to investigate the chemical composition of distillery yeast sludge and its inclusion in broiler diets to replace canola meal. Raw distillery yeast sludge was washed with water using water and sludge in the ratio 6:1, respectively. Proximate analysis of raw distillery yeast sludge and washed distillery sludge was carried out for crude protein (CP), true protein (TP), ethe...

A fixation-free and fast protein-staining method for sodium dodecyl sulfate-polyacrylamide gel electrophoresis using Coomassie blue is described. The protocol comprises staining and quick washing steps, which can be completed in 0.5 h. It has a sensitivity of 10 ng, comparable with that of conventional Coomassie Brilliant Blue G staining with phosphoric acid in the staining solution. In additio...
