| 摘 要： | 研究了吸附时间、飞灰用量、初始溶液pH和振荡频率等因素对飞灰吸附去除水溶液中磺胺的影响,并对其吸附机理进行了初步探讨。研究结果表明,飞灰用量增大有利于提高其对磺胺的吸附去除率。在25℃、振荡频率150 r/min、飞灰用量50 g/L、磺胺浓度4 mg/L条件下吸附10 min,磺胺的吸附去除率可达到92.8%。电厂飞灰对磺胺的吸附符合二级动力学模型,属于单分子层吸附。

| Abstract: | Effects of adsorption time, fly ash dosage, pH, adsorption temperature and oscillation frequency on adsorption-removal for sulfonamide were researched, and its adsorption mechanism of fly ash for sulfonamide was simplely studied. The results showed that the adsorption-removal rate increased with the increasing of fly ash dosage. Under the conditions of fly ash dosage of 50 g/L, sulfonamide of 4 mg/L and 150 r/min for 10 min, the adsorption-removal rate of sulfonamide was 92.8%. Its adsorption mechanism for sulfonamide by fly ash fitted second kinetic model, and belonged to monolayer adsorption. |
