摘要
以农业废弃物丝瓜络为基材,乙酸酐为酯化剂,在微波条件下制备了一种新型吸附材料,分析其对MB的吸附性能。研究结果表明,在pH为6~7,MB浓度为5.00mg/L,材料投加量为3g/L,温度为25℃,振荡时间为120min条件下,改性丝瓜络对MB的处理效果最佳,去除效率为98.7%。改性丝瓜络对MB的吸附行为遵循准二级动力学规律。
Using agricultural waste loofah as the substrate and acetic anhydride as the esterification agent,a new type of adsorption material was prepared under microwave conditions,and its adsorption performance for MB was studied.The research results show that under the conditions of pH 6~7,MB concentration 5.00mg/L,material dosage 3g/L,temperature 25℃,and shaking time 120min,the treatment effect of modified loofah on MB was the best.The removal efficiency was 98.7%.The adsorption behavior of modified loofah on MB follows the pseudo-second-order kinetic law.
