Abstract
In this study, the dye removal of acid and metal complex dyes (Acid Black 26 and Acid Yellow 59) by electrocoagulation process using aluminum electrodes were studied at single and binary systems. The effect of several operating parameters such as conductivity, current density, initial dye concentration and pH on the electrocoagulation process was studied. The Beer-Lambert’s law has been applied to the binary system analysis by spectrophotometer and measurements at two wavelengths for each sample have led to determine the concentration and extinction coefficient of the two components at their maximum wavelength. It was found that increasing the current density has a positive effect on color removal efficiency. It was also indicated that increasing conductivity, did not have a significant effect on color removal efficiency but decreased the cell voltage. The most important result is that the data for single and binary systems are too close and it can be concluded that the electrocoagulation process is an effective method to remove acid and metal complex dyes from single and binary systems.
