Background and purpose: Textile effluents are very difficult to treat satisfactorily due to high variations in their compositions. Strong color is one of the main characteristics of textile effluent and, if not eliminated, it can cause serious problems to the environment. In the present study, multi-walled carbon nanotubes (MWCNTs) were used as an adsorbent for the removal of Reactive Red-120 (...

Herein we report superior dye-adsorption performance for flower-like nanostructure composed of two dimensional (2D) MoS2 nanosheets by a facile hydrothermal method, more prominent adsorption of cationic dye compared with anodic dye indicates the dye adsorption performance strongly depends on surface charge of MoS2 nanosheets. The adsorption mechanism of dye is analyzed, the kinetic data of dye ...

fe3o4 magnetic nanoparticles modified with 1-octyl-3-methylimidazolium bromide([c8mim]-fe3o4) were used for the removal of reactive red 141 (rr141) and reactive yellow 81 (ry81) as model azo dyes from aqueous solution. the mean size and the surface morphology of the nanoparticles were characterized by tem, xrd and ftir techniques. adsorption studies of two dyes were performed under different ex...

This study was designed to investigate the removal of reactive violet 48 from wastewater using Commercial activated carbon and Coir pith activated carbon. Its adsorption capacity has been tested for the decolourization of waste water containing reactive violet 48. The effect of system variables such as concentration, temperature, contact time and pH were studied. The adsorption data follow Lang...

The current commercial application of ink-jet reactive inks to cotton fabrics has been through pre-treating with pad liquor prior to printing. In This study made an effort to provide a single phase ink-jet printing process for printing cotton fabric using the novel cationic reactive dye in ink’s formulation. Cotton fabric was printed upon with the novel cationic reactive dye and commercial anio...
