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