Adsorption of toxic crystal violet dye using (Chitosan- OMWCNTs) from aqueous solution

Abstract Crystal Violet dye is a toxic organic pigment that has little solubility in water and causes serious health problems environmental pollution. In the current study, compound composed of multi-walled carbon nanotubes with chitosan was used. Experiments were conducted to adsorb crystal violet for both effect surface weight adsorbent contact time. Dye CS-OMWCNTs. And study pH ionic intensity removing dye. The results are shown. best obtained as an 0.035 g. showed time reach state balance, which 90 minutes. By studying pH, acid medium pH=4 percentage deletion 99% acidic concentration 100 ppm. As each salts sodium chloride potassium carbonate studied. adsorption decreases salt ions compete active sites
