Dye-containing wastewater is one of the main environmental challenges that can cause health issues. It is crucial to remove the dyes from wastewater before its discharge into the environment. This study aims to evaluate the efficiency of aptenia cordifolia mucilage in removal of anionic dyes from textile wastewater via coagulation and flocculation process. To this goal, the effect of different ...

abstract background and purpose:the main objectives of this research were to evaluating the application of electrocoagulation process for 198 dye from the aqueous phase and determining the optimum operating conditions to the dye removal using aluminum and iron electrodes. materials and methods:the present study was conducted in bench-scale. the spectrophotometer dr 5000 was used to determine th...

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...

this paper deals with application of polyaniline coated on wood sawdust for removal ofmethylene blue (mb) dye from aqueous solutions. polyaniline coated onto sawdust (termedas pan/sd) was prepared via direct chemical polymerization onto sawdust which waspreviously soaked in the monomer (aniline) solution in acidic (hc1) media. adsorptionexperiments were carried out using batch system. the effec...

Skin exposure to permanent hair dye compounds was assessed in 33 hairdressers using a previously evaluated hand rinse method. Hand rinse samples were collected from each hand before the start of hair dyeing, after application of the dye and after cutting the newly-dyed hair. Sixteen of the hairdressers did not use gloves during dye application, and none used gloves while cutting the dyed hair. ...
