Spectral Study of Aggregation Behavior of Remazol Brilliant Violet-5r Dye in Cationic Ligand Solutions

Ashraf El-Hashani, Abdelmeneim El-Dali & Khaled M. Elsherif · Chemical Science International Journal · 2015

An UV-VIS spectrophotometric investigation has been made to study the interaction and aggregation of anionic remazol brilliant violet-5R (RBV-5R) dye in acidic ethanol amine and tallow amine solutions. As a consequence of increasing the concentration of ethanol amine, the maximum...

Spectral Studies of Eriochrome Black T in Cationic Surfactants

Khaled Edbey, Ashraf El-Hashani, Abdelhadi Benhmid, Kamal Ghwel & Mohamed Benamer · Chemical Science International Journal · 2018

The critical micelle concentration (CMC) for a series of cationic surfactants N-Alkyltrimethylammonium i.e. (CnTAC, n=12, 14, 16, 18) have been determined by electrical conductivity and surface tension methods. The interaction of anionic dye Eriochrome Black T (EBT) with cetyl-tr...
