Color Fading Behavior of C.I. Disperse Blue 3 by NO2 Gas.

Decolorization and Degradation of Basic Blue 3 and Disperse Blue 56 Dyes Using Fenton Process

In this study, oxidative discoloration of Basic blue3 (B.B3) and Disperse blue56 (D.B56) dyes in synthetic textile wastewater has been studied using Fenton (Fe2+/H2 O2 ) process. The Fenton’s technique showed satisfactory color removal efficiency. The operating parameters such as concentration of Fe2+, dose of H2 O2 , initial concentration of dye, time contact, initial volume of wastewater that...

decolorization and degradation of basic blue 3 and disperse blue 56 dyes using fenton process

Decoloration of Disperse blue 56 by Using of UV/H2O2/MWCNT’s

In this study, the oxidation of dye from colored wastewater by H2O2/ MWCNT’s multi walls carbon nano tubes solution assisted with UV radiation was investigated. Disperse Blue 56 DB 56 was used as a model dye. Adsorption behavior of DB56 from aqueous solution onto MWCNT’s was investigated under various conditions such as initial pH value, dye concentration, H2O2 and MWCNT’s dosage. Maximum adsor...

Crystal structure of a methine dye, C.I. Disperse Blue 354.

Crystals of C.I. Disperse Blue 354, a commercial methine disperse dye, were grown from an ethyl acetate and the crystal structure was determined. Results show that two aromatic planes are effectively coplanar with the dihedral angle of 10.61(11) degrees. The dicyanomethylene group is slightly twisted and two n-hexyl groups tend to be separated with one alkyl group being at the level of the arom...

Decoding the fading of Prussian blue pigment

for art history issues. The task is complex however because of the highly heterogeneous character of a paint layer, which consists of a mixture of pigments and a binder on a support. All the components interact and infl uence the ageing process of the paint layer. The work described here is focused on understanding the discoloration over time of a particular pigment, Prussian blue, a synthetic ...
