A Study on Removal of Styphnic Acid in Aquatic Environment by Using UV-H2O2/nano TiO2
Main Article Content
Abstract
Abstract: The research focused on survey application capability of optical catalyst nano TiO2 foroxidationstyphnic acid (TNR) in wastewater by UV-H2O2. The affect of reaction conditions including times (0-90 minute), pH, wavelength of UV, molar ratios H2O2/TiO2, temperature, initial concentration on removal efficiencis of TNR were examined. Consequenceof CTNR= 154,4 mg/L, molar ratios as H2O2/TiO2 = 15, pH=3 and wavelength UV= 313nm resulting 100% TNR was treated after 90 minute reaction. The temperatures in ranged of 30-50oC were not significantly effectedthe TNR removal efficiency.
Keywords: TNR, axit stynic, UV- H2O2, nano TiO2, removal.
