| 摘 要： | 以黄麻纤维为原料，采用磷酸活化法制备活性炭。研究黄麻纤维活性炭对亚甲基蓝和甲基橙2种染料的吸附行为。结果表明，采用磷酸制备的活性炭，由于表面含有羧基和含磷官能团等酸性基团，能够促进活性炭对亚甲基蓝的吸附；黄麻纤维活性炭对2种染料的平衡吸附量、初始吸附速率均随着初始浓度的增加而升高；相同条件下，黄麻纤维活性炭对亚甲基蓝的平衡吸附量大于甲基橙；黄麻纤维活性炭对两种染料的吸附行为更符合准二级动力学模型。

| Abstract: | Jute fiber-based activated carbon (JFAC) were prepared by using jute fibers as raw materials and phosphoric acid as activating agent. The adsorption behaviors of JFAC on methylene blue (MB) and methyl orange (MO) dyes were investigated. Results showed that JFAC prepared by phosphoric acid activation had good adsorption capacity on MB due to the acidic groups such as carboxyl and phosphorus-containing functional groups on their surfaces. The equilibrium adsorption capacity and the initial adsorption rate of JFAC on MB or MO increased with increasing of initial concentration. Under the same condition, the adsorption capability of JFAC on MB was greater than that on MO. Besides, the adsorption behaviors of JFAC on both MB and MO fitted well with Pseudo-second-order kinetic model. |
