Excited‐state proton transfer (ESPT) photochemical reactions are attracting increasing attention because of their many applications in materials science and biology. 2‐Mercaptobenzothiazole (MBT) is investigated in solid, protic, and aprotic solvents using vibrational and electronic spectroscopies combined with density functional theory (DFT). The presence of the stable dimer conformer in the solid...
A three-dimensional electrode reactor combined with Fenton's reagent was used for advanced treatment of coking wastewater from secondary biological treatment. Effects of some key factors on TOC removal rate were investigated and kinetics of coking wastewater was also studied under certain the operating parameters of the three-dimensional electrode reactor. The orthogonal test results showed that the...
In this study, decolorization and chemical oxygen demand (COD) reduction of coking wastewater by electrocoagulation process has been investigated. Effects of operating parameters, such as current density, pH of solution, electrolyte concentration and hydraulic residence time (HRT) on decolorization by continuous electrocoagulation were further studied in order to optimize process performance. The...
The coking wastewater drainage will bring severe water environmental pollution, so reuse of post-treatment coking wastewater as make-up water for circulating cooling system is an important way. Electrochemical oxidation combined flocculation technology was proposed for treating coking wastewater. The effects of the electrolytic voltage, current density, electrode distance, pH value, electrolytic time,...
