catalytic wet peroxide oxidation of hydroquinone with co(ⅱ)/active carbon catalyst loaded in static 免费下载-米乐app官方

catalysts based on co(ⅱ) supported on active carbon were prepared and loaded in static bed.the hydroquinone wouid be degraded completely after treated by catalytic wet peroxide oxidation method with co(ⅱ)/active carbon catalyst.after activate treatment, the active carbon was immerged in cobaltoas nitrate solution, then put into a drying oven, co(ⅱ) could be loaded on the micro-surface of carbon.taking the static bed as the equipment, the absorption of active carbon and catalysis of co(ⅱ) was used to reduce activation energy of hydroquinone.thus hydroquinone could be drastically degraded and the effluent can be drained under the standard.referring to fenton reaction mechanism, experiment had been done to study the heterogeneous catalyzed oxidation mechanism of co(ⅱ).the degradation rate of hydroquinone effluent could be achieved to 92% when treated in four columns at h2o2 concentration 10%, reaction temperature 40℃, ph 5 and reaction time 2.5h.
