“…Partial oxidation of intermediate compounds could minimize the consumption of chemical reagents and result in substantial reduction of COD and toxicity. Additionally, higher biological activity of degradable low molecular weight components was in favor of the further biological treatment [9,22]. So the optimal reaction time should be 2 h when both the COD removal and B/C value were taken into consideration.…”

“…COD was measured according to the standard dichromate titration method. To eliminate interference from H 2 O 2 in COD measurement, the H 2 O 2 concentration was determined spectrophotometrically using titanium oxalate [31], and then subtracted from the COD calculation. A blank experiment was conducted simultaneously.…”

In this study, photo-Fenton oxidation was applied to degradation of sulfamonomethoxine sodium (SMMS) in aqueous solution. The operation parameters of pH, temperature, and concentrations of H 2 O 2 , Fe 2+ and SMMS were investigated. The optimum conditions for the photo-Fenton process were determined as follows:.51 mol/L and T=25°C. Under these conditions 98.5% of the SMMS degraded. The kinetics were also studied, and degradation of SMMS by the photo-Fenton process could be described by first-order kinetics. The apparent activation energy was calculated as 23.95 kJ/mol. Mineralization of the process was investigated by measuring the chemical oxygen demand (COD), and the COD decreased by 99% after 120 min. This process could be used as a pretreatment method for wastewater containing sulfamonomethoxine sodium.sulfamonomethoxine sodium, degradation, photo-Fenton

“…and H 2 O 2 in sonolysis has been proven as an effective method to degrade refractory compounds (Ling et al, 2010;Lin et al, 2013), exceed chemical dosages in the reaction are disadvantage to the oxidation process and the degradation efficiency might be decreased (Vamathevan et al, 2001;Sun et al, 2009). The "additional dosages" is generally defined as the further increases in H 2 O 2 and Fe 2+ dosages in solution leads to the self-competition to catch the OH then the produced OH was worthless to react with the pollutants.…”

Tetracycline is named by its four special benzene rings in molecular structure, which has been proven as a strong inhibition chemical for many kinds of bacterial. To solve the problem of residual tetracycline containing in municipal and medicine industrial wastewater effluents, this study tried to combine the ultrasound with transition metals ( .9% of tetracycline were degraded and mineralized. In addition, the toxicity was significantly reduced while the cell viability increased from 53.1% (un-treated) to 87.5% (treated). Effect of pH on the degradation of tetracycline in this study was insignificant but pH 3 showed the better efficiency. It was concluded that the enhanced sonolysis was effective on the degradation, mineralization and detoxicity of tetracycline solution.
