Photodegradation of the antibiotic sulphamethoxazole in water with UV/H2O2 advanced oxidation process.
Photodegradation of the antibiotic sulphamethoxazole (SMX) in water using a medium-pressure UV lamp combined with H2O2 (UV/H2O2) was used to generate the advanced oxidation process (AOP). The photodegradation process was steadily improved with addition of H2O2 at relatively low to moderate concentrations (5 to 50 mg L(-1)). However, the addition of H2O2 to the photolysis process at higher conce...
متن کاملDecomposition of Anionic Sodium Dodecylnemzene Sulfonate by UV/TiO2 and UV/H2O2 Processes a- Comparison of Reaction Rates
Anionic DBS surfactant can be photodegraded in a TiO2 dispersion and H2O2 solution under an Hg-lamp (15 W) UV illumination or solar exposure. Degradation process has been monitored through cleavage of aromatic moiety. Degradation of the detergent was small when the photolysis was carried out in the absence of TiO2 and H2O2 an...
متن کاملThe alkaline anthraquinone-2-sulfonate-H2O2-catalyzed oxidative degradation of lactose: an improved Spengler-Pfannenstiel oxidation.
The alkali-catalyzed oxidative degradation of lactose (1) to potassium O-beta-D-galactopyranosyl-(1----3)-D-arabinonate (2) has been studied and compared with that of D-glucose to D-arabinonate and D-galactose to D-lyxonate. A mechanism for the degradation of 1 catalyzed by alkali only is presented and discussed, taking into consideration the main reaction products. Increasing the reaction temp...
متن کاملEffect of H2O2 dosing strategy on sludge pretreatment by microwave-H2O2 advanced oxidation process.
Considering characteristics of breaking down H(2)O(2) into water and molecular oxygen by catalase in waste activated sludge (WAS), the effect of H(2)O(2) dosing strategy on sludge pretreatment by the advanced oxidation process (AOP) of microwave-H(2)O(2) was investigated by batch experiments for optimizing H(2)O(2) dosage. Results showed that the catalase in sludge was active at the low tempera...
متن کاملApplication of H2O2 and H2O2/Fe0 in removal of Acid Red 18 dye from aqueous solutions
Background & Aims of the Study: Organic dyes with a complex structure are often toxic, carcinogenic, mutagenic, non-biodegradation and stable in the environment and if released to the environment without treatment can endanger the environment and human health. The aim of this study was to evaluate the performance of H2O2 and H2O2/Fe0 Iron in removal of dye Acid Red 18 from aque...
