Decolorization of sunset yellow dye (SY) in an aqueous solution was investigated by Fenton reaction using H2O2/Fe 2+ system. Different parameters controlling the degradation efficiency as pH and H2O2 and Fe 2+ concentrations were evaluated. The optimal operational conditions were found to be [Fe] = 2.55x10 mmol, [H2O2] = 0.2425 mmol at pH 2.7. The study of the Kinetics of decolorization indicat...

The interaction of small molecules with larger non-covalent assemblies is important across a wide range of disciplines. Here, we apply two complementary NMR spectroscopic methods to investigate the interaction of various fluorophenol isomers with sunset yellow. This latter molecule is known to form non-covalent aggregates in isotropic solution, and form liquid crystals at high concentrations. W...

Interfacial polymerization of polyamide was conducted using hydrophobic and hydrophilic membrane support. The effects monomer concentration were investigated, the resulting thin-film composite membranes tested for their performance in dye removal different flow configurations. results showed that a dense layer successfully formed on support, while with very loose structure became smoother more ...

We have performed the present piece of work to evaluate the effect of synthetic food coloring azo dye (sunset yellow) on actively dividing root tip cells of Brassica campestris L. Three doses of azo dye were administered for the treatment of actively dividing root tip cells, namely, 1%, 3%, and 5%, for 6-hour duration along with control. Mitotic analysis clearly revealed the azo dye induced end...
