Dye removal from industrial wastewater is an important environmental concern. So far, various physical and chemical treatment methods have been reviewed for the removal of dyes such as biological degradation, ion exchange, chemical precipitation, reverse osmosis, coagulation, flocculation, etc. However, these treatment processes have their limitations such as high cost, generation of toxic slud...

In this paper, the use of surfactants for solubilization of hydrophobic organic dyes (mainly solvent and disperse dyes) has been reviewed. The effect of parameters such as the chemical structures of the surfactant and the dye, addition of salt and of polyelectrolytes, pH, and temperature on dye solubilization has been discussed. Surfactant self-assemble into micelles in aqueous solution and bel...

Dye-loaded polymeric nanoparticles (NPs) are promising bioimaging agents because of their available surface chemistry, high brightness, and tunable optical properties. However, dye loadings can cause the aggregation-caused quenching (ACQ) encapsulated fluorophores. Previously, we proposed to mitigate ACQ inside NPs by insulating cationic dyes with bulky hydrophobic counterions. In order impleme...

Two-dimensional (2D) Molybdenum disulfide (MoS 2 ) has become one of the most exciting areas research for adsorbents due to its high surface area and abundant active sites. Mainly, 2D MoS show promising removal textile dye pollutants by adsorption process, but it affinity anionic type dyes, that limits performance in mixed treatment. Herein, we demonstrate an integrated approach remove (anionic...

Polyvinylidene fluoride (PVDF)/g-C3N4/Chitosan thin film membranes were prepared by immersing of PVDF/g-C3N4 membrane in solution containing various concentrations chitosan for removal Direct Blue 14 dye (an anionic dye) from aqueous solutions. The resulting characterized XRD, FESEM, TEM and AFM. Also, pure water flux, salt rejection, content antifouling properties investigated. demonstrate tha...

Polypyrrole globules, nanofibers and nanotubes were activated by their carbonization at 650 °C in the 3:1 mass excess of molten potassium hydroxide argon. They have been compared with parent polypyrroles analogous samples obtained absence hydroxide. The yields after activation, 12–18 wt%, lower to carbonization, which exceeded 50 wt%. changes molecular structure are discussed on basis FTIR Rama...
