Study on treatment 2-DIAZO-4,6-DINITROPHENOL (DDNP) in waste water using UV-H2O2/TiO2

Abstract

This study focuses on investigating the ability to decompose DDNP in water by UVH2O2/red mud Tay Nguyen. The research was conducted on the basis of determining the decomposition efficiency of DDNP in water under different conditions such as H2O2 / TiO2 ratio, initial DDNP concentration, pH, UV wavelength and UV intensity. Research results show that at the initial concentration of DDNP equal to 200 mg/L, the molar ratio of H2O2/ TiO2 = 15, pH = 3, λ = 185 nm, 98.56% DDNP decomposes after 120 minutes.
