Abstract:   (1181 Views)

Background & Objectives: Cationic dyes such as basic violet have various applications in different industries. This experimental study was conducted to investigate degradation of basic violet by fenton process.

Methods: To establish cost-efficient operating condition for potential application of fenton oxidation process, the influence of the main operating parameters such as iron sulphate and hydrogen peroxide doses, solution pH, and initial dye concentration have been studied in a laboratory scale.

Results: Complete removal of dye at initial concentration of 30 mg/L was obtained after 8 mins by fenton process. The optimum levels of iron, hydrogen peroxide and pH for complete removal of dye were determined at 0.4 mmol/L, 17 mmol/L, and 3, respectively. Every increase in concentration of dye leaded to a decrease in degradation rate. The results indicate that 99% decolorization and about 58% reduction in COD are achievable by fenton process. Other finding indicates that kinetic data to follow well the fake second order equation.

Conclusion: Regarding the results of this study fenton process can be used as an effective method to remove basic violet 16 and other resistant dyes from aqueous solutions

Keywords: Basic Violet 16, Advanced Oxidation, Aqueous Solutions.
