焦粉吸附处理吲哚溶液试验研究
|
摘要
焦粉对焦化废水中包括吲哚在内的有机污染物具有较好的吸附作用,为进一步提高焦粉对吲哚的去除率,以2 mol/L硝酸为改性剂对原焦粉(CP-Raw)进行改性得到硝酸改性焦粉(CP-HNO_3),分别用2种焦粉对吲哚溶液进行吸附处理,选择吸附效果较好的焦粉进行优化试验,同时对2种焦粉的物理化学性质进行表征和对比。试验结果表明,焦粉经改性后理化性质发生改变且吸附性能提高;使用CP-HNO_3在最佳试验条件下,吸附处理吲哚溶液能够得到很高的吲哚去除率。
Coke powder has good adsorption effect on organic pollutants, including indole, in coking waste water. In order to improve the coke removal rate of indole, HNO_3 with a concentration of 2 mol/L was used as modifier to modify coke powder(CP-Raw) and obtain modified coke powder(CP-HNO_3),and two kinds of coke powder were used to adsorb indole solution. The coke powder with good adsorption effect was selected to optimize the experiment, and the physical and chemical properties of the two coke powders were characterized and compared. The test results show that CP-HNO_3 has some changes in physical and chemical properties and the adsorption property has been improved; under the optimum experimental conditions, a high removal rate of indole can be obtained using CP-HNO_3 to treat indole solution.
