摘    要:通过一系列实验,探讨了粉末活性炭吸附水中苯酚时,腐殖酸(HA)浓度和细颗粒泥沙用量对苯酚吸附量和去除率的影响.实验结果表明:在中性条件下,随着HA浓度的增加,粉末活性炭对苯酚的吸附量减少;在不同质量细颗粒泥沙的影响下,苯酚的去除率基本不变;在未加HA时,粉末活性炭对苯酚的吸附行为用Langmuir吸附等温式拟合效果最好,对苯酚的最大吸附量为150.60 mg/g,而在有HA存在时,粉末活性炭对苯酚的吸附行为用Freundlich吸附等温式拟合效果最好,对苯酚的最大吸附量为28.49 mg/g.

关 键 词:活性炭  苯酚  腐殖酸  细颗粒泥沙  吸附等温线

Abstract:Effects of concentrations of humic acid and of fine grain sediment on adsorption of phenol on activated carbon were studied. The adsorptive capacity of activated carbon for phenol declined with increasing concentration of humic acid that was also present; the amount of fine grain sediments had little effect on the phenol capacity. Using the Langmuir adsorption isotherm, the maximum capacity for phenol was 150.60 mg/g; it was reduced to 28.49 mg/g when 25.0 mg/L of humic acid was present.
Keywords:Activated carbon Phenol Humic acid Fine grain sediment Adsorption isotherm
