【摘要】：以太西煤和兰炭为原料,利用水热法制备出相应的磺化材料,壳聚糖与磺化太西煤、兰炭通过静电自组装方法制备出磁性磺化炭基复合材料,用于吸附废水中的苯酚。探究了pH值、吸附时间、温度、模拟废水初始浓度等对磁性磺化炭基复合材料吸附苯酚的影响。结果表明,磁性磺化太西煤复合材料在pH=5,反应时间2 h,反应温度45℃及苯酚初始浓度10 mg/L时,苯酚吸附率达98.01%;磁性磺化兰炭复合材料在pH=5,反应时间4 h,反应温度35℃及苯酚初始浓度10 mg/L时,苯酚吸附率达62.44%。
[Abstract]:The corresponding sulfonated materials were prepared by hydrothermal method from etheric coal and blue charcoal. The magnetic sulfonated carbon matrix composites were prepared by electrostatic self-assembly of chitosan and sulfonated coal. The effects of pH value, adsorption time, temperature and initial concentration of simulated wastewater on the adsorption of phenol by magnetic sulfonated carbon matrix composites were investigated. The magnetic sulfonated Texi coal composites were prepared at pH 5, reaction time 2 h, reaction temperature 45 鈩，
