The classification of textile dyes has become essential due to the remarkable increase in the
type and number of dyes. The structural classification of these dyes can be determined by …

In this work, we have presented a very detailed review of the different classification of azo
dyes as a function of the number of azo groups and the appropriate functional groups. Then …

Abstract Azo dyes, including Tartrazine, Sunset Yellow, and Carmoisine, are added to foods
to provide color, but they have no value with regard to nutrition, food preservation, or health …

Dyes play a crucial role in various industries, but their environmental impact and potential
health risks have raised concerns. This review paper examines the classification and …

Abstract (E)-1-[(2, 4, 6-Tribromophenyl) diazenyl]-naphthalen-2-ol azo dye, an organic
crystal, was fully characterized by three reliable spectroscopic techniques (Fourier-transform …

Novel Polyetherimide (PEI) composite membrane has been investigated to improve the
mechanical and antifouling properties. In this study, the preparation and properties of …

Two new organic dyes (SD-1 and SD-2) featured with donor–π–acceptor architecture were
synthesized and applied to dye-sensitized solar cells (DSSCs). In these sensitizers, an azo …

Microorganisms have great potential for bioremediation as they have powerful enzymes and
machineries that can transform xenobiotics. The use of a microbial consortium provides …

Abstract Four novel 3-aryl-2-cyano-N'-(4-(diphenylamino) benzylidene) acrylohydrazide
dyes 5–8 were developed, synthesized, and evaluated as sensitizers for dye-sensitized …
