The present research provides data on the density (ρ), viscosity (η) and ability to absorb carbon dioxide of systems containing amine, molecular solvent (MS) choline chloride (ChCl), with investigation physical properties both neat amine/MS/ChCl mixtures their samples after complete CO2 saturation. effect mixture composition was studied by varying amine from primary (monoethanolamine, MEA) seco...

Photocatalytic degradation of phenol by oxidation, utilizing doped TiO2 (Fe/TiO2) as photocatalyst in the form of immobilized thin films in a jacketed photocatalytic batch reactor was the subject of this research. Fe/TiO2 photocatalyst was successfully synthesized using sol-gel method and coated on the chosen glass substrates using the wet coating method of dip-coating. Titanium isopropoxide wa...

The photosensitization of microorganisms is potentially useful for sterilization and for the treatment of certain bacterial diseases. Until now, any broad spectrum approach has been inhibited because, although Gram-positive bacteria can be photoinactivated by a range of photosensitizers, Gram-negative bacteria have not usually been susceptible to photosensitized destruction. In the present work...

A new substrate, ammonium thymolphthalein monophosphate, is proposed for use in alkaline and acid phosphatase determinations. The ammonium salt shares the advantages of the sodium salt, but is a more stable substrate and results in more stable working reagents. The substrate is buffered at ph 10.1 in diethanolamine for determining alkaline phosphatase activity in 5 mm, and at pH 5.9 in citrate ...

The present study focused on stress corrosion cracking (SCC) and corrosion behavior of ferritic stainless steel (grade 430) in activated methyl diethanolamine (aMDEA) solution, which is classified as a tertiary amine. In this regard, cyclic polarization and U-bend tests were performed in CO2 loaded aMDEA with different concentrations at 25 and 70 °C to observe corrosion behavior and ...

In this work, a new synthesized Y-type zeolite with an Si/Al molar ratio of 2.5 (NaY) was modified with amines, in order to probe the influence of the modification of the adsorbent’s surface on CO2 adsorption. The three selected amines were diethanolamine, tetraethylenepentamine, and 2- methylaminoethanol. The surface nature of NaY was changed after amine modification, which causes a...

Titanium dioxide is semiconductor metal oxide having many applications in photocatalytic activities, cosmetics and in the food industry. It exists in three major crystalline forms: anatase, rutile and brookite. The solvents play a major role in the synthesis, stability and morphology of the metal oxide nanoparticles. It affects both the phase and particle size of metal oxide. T...
