| Popis: | This paper deals with the optimization of alkali-clearing process of a novel alkali-clearable disperse dye and the investigation of its removal from the dyeing wastewater. The response surface methodology was used for the optimization of alkali-clearing process of the dyed polyester fibers. The results have clearly shown that the synthesized disperse dye has reasonable level of hydrolysis under relatively mild alkaline condition. It was also found that the adsorbed dye molecules would be removed from the fibers using a simple alkali-clearing process rather than the conventional methods being employed. In order to study the environmental aspects of the synthesized disperse dye, its removal process was investigated by the electrocoagulation method using iron as electrodes. The effect of operating parameters such as current density, conductivity, initial dye concentration, and pH on the removal efficiency were examined. Moreover, the results showed that the electrocoagulation process with low cost an... |
