Background and purpose: Çhemical dyes used in textile industries involve some potential risks including carcinogenic and mutagenic effects in human. Furthermore, penetration of different dyes into surface and groundwater is a source of color in water reservoirs. This study aims at investigating the removal efficiency of yellow 3 and disperse yellow 3 reactive dyes by combined ÇÂÇ-SBR system. ...
this paper reports application of cetyltrimethylammonium bromide (ctab) coated magnetite nanoparticles (fe3o4 nps) as a novel adsorbent for removal of two types of disperse dyes, including disperse red 167, and disperse blue 183, from wastewater of textile companies. the effect of parameters including type of surfactant, ph of solution, surfactant concentration, and amount of salt, was investig...
Resonance Raman spectra of azobenzene derivatives were examined in the presence of lipid membranes to find a probe that can distinguish different membrane phases. The NO2 symmetric stretching band of 4-(4-nitrophenylazo)aniline, also known as Disperse Orange 3 (DO3), is downshifted by about 4 cm(-1) on the phase transition of phosphatidylcholine membranes from the liquid crystalline to the gel ...
The averaged dynamics of various two-phase systems in a high-frequency vibration field is studied theoretically. The continuum approach is applied to describe such systems as solid particle suspensions, emulsions, bubbly fluids, when the volume concentration of the disperse phase is small and gravity is insignificant. The dynamics of the disperse system is considered by means of the method of a...
