活性碳纤维对水中喹啉的吸附性能
Adsorption characteristics of quinoline on activated carbon fiber
摘要
Abstract
The static adsorption of quinoline on activated carbon fiber (ACF) was studied. The factors effecting adsorption efficiency and behaviors such as time, quinoline does, temperature, pH and organic compound were investigated. The results show that quinoline adsorption capacity on ACF was up to 210 mg/g at higher concentration and adsorption efficiency decreased with an increase of temperature. It was found that ACF had good adsorption properties when pH<7. The presence of organic substances inhibits the sorption efficiency. The adsorption isotherms conform to Langmuir adsorption isotherm and the adsorption process fits a pseudo-second-order model. The sorption parameters Δ/f° and ΔG° were both negative, so the adsorption is spontaneous and exothermic. Scientific basis is offered for environment function material ACF using in industrial production. Based on the experimental results, dynamic adsorption experiment and treatment of coke plant wastewater is necessary. In addition, the problem of the respect such as high cost and desorption regeneration of ACF remain to be further studied.关键词
