The molecular structure, UV-visible spectra, and optical properties of D-π-A conjugated organic dye molecules (Disperse Red 1 (DR1) Disperse 73 (DR73)) were analyzed using density functional theory (DFT) time-dependent (TD-DFT) compared with azobenzene molecule to study the effect donor acceptor substituents on properties. performance DFT functionals is investigated B3LYP hybrid three long-rang...

A series of disperse dyes, 9,10-anthraquinone containing dithiocarbamate, thiourea and triazole fragments, were prepared via consecutive refunctionalization aminoanthraquinones in our previous studies their structures confirmed by the 1H-, 13C-NMR, IR spectra, LC-MS elemental analysis data. The obtained compounds applied on polyester fabrics exhaustion method at 130?C pH 4.0-5.0, dyeing propert...

In this study, a combined electro-(Fenton/coagulation/flotation) (EF/EC/El) process was studied via degradation of Disperse Orange 25 (DO25) organic dye as a case study. Influences of seven operational parameters on the dye removal efficiency (DR%) were measured: initial pH of the solution (pH0), applied voltage between the anode and cathode (V), initial ferrous ion concentration (CFe), initial...

Degradation of 29 dyes by means of an activated carbon fiber (ACF) electrode electrolysis system was performed successfully. Almost all dye solutions tested were decolorized effectively in this ACF electrolysis process. Internal relationships between treatment mechanisms and chemical composition of the dye have been discussed in this paper. Generally, it is shown that higher solubility leads to...
