微波诱导催化氧化法降解溴氨酸水溶液影响因素研究

采用微波诱导催化氧化工艺对溴氨酸水溶液的降解进行了初步研究,考察了H2O2投加量、溴氨酸水溶液初始浓度、催化剂投加量、微波辐照功率及微波辐照时间等因素对溴氨酸降解效果的影响.实验结果表明:加入9 g改性氧化铝催化剂于100 mL浓度为400 mg/L溴氨酸水溶液中,在微波功率为640 W,辐照时间为1 min,H2O2用量为4 mL的条件下,溴氨酸水溶液的脱色率达92.3%,CODCr去除率达87.7%.

Research on Degradation of Bromine Acid Aqueous by Microwave Induced Oxidation Process

Microwave-induced catalytic oxidation process is used to conduct the preliminary study on bromine acid solu-tion degradation.Influence of H2O2 dosage,bromine acid solution initial concentrationt,he amount of catalyst,power mi-crowave radiation,and microwave irradiation time on the bromine acid degradation effect were inspected.Result shows that CODCr removal rate reached 87.7% with the adding of 9,g modified alumina catalyst at 100,mL concentration of 400 mg/L bromine acid solution,the microwave power of 64...
