Abstract

In this research, a new method was developed for direct determination of Reactive Orange 84 in aqueous solutions during electreooxidation degradation in presence of titanium dioxide nanoparticles. Firstly, analytical parameters of two methods the spectrophotometry and electrochemistry was compared to choose the best method for determination of dye in aqueous. The electrochemical measurements of dye conducted out by glassy carbon electrode modified by graphene oxide and silver nanoparticles. The results shown that the Electrochemical method is capable determinate very low concentrations of dye (20. 0 nM) compared with spectrophotometry (4. 8 μ M) even in the presence of suspended particles in the solution. The proposed method has a linear range of 0. 05 to 100. 0 μ M toward concentrations from Reactive Orange 84. The effect of presence of different dyes and interfering ions on performance the proposed method in the dye measurement was investigated. In addition, presented method was successfully applied to RO84 detection in wastewater samples collected from two textile plant. J. Color Sci. Tech. 12(2018), 81-92© .
