以黄麻纤维和黄麻杆为原料,采用磷酸活化法制得两种黄麻基活性炭作为吸附剂,以亚甲基蓝染料溶液为吸附质,探讨了染料溶液初始质量浓度、活性炭投加量、吸附时间、水浴温度、染料溶液pH值等因素对黄麻基活性炭吸附性能的影响.结果表明:随着染料溶液初始质量浓度的增加,亚甲基蓝去除率逐渐降低,吸附量逐渐增大;随着活性炭投加量的增加、吸附时间的延长或染料溶液pH值的增加,亚甲基蓝去除率和吸附量均呈现逐渐增大的变化趋势;水浴温度对亚甲基蓝去除率和吸附量影响较小.黄麻杆活性炭因具有较大的比表面积和总孔容,其对亚甲基蓝的去除率和吸附量高于黄麻纤维活性炭.
Abstract：Jute fibers and jute sticks are used as raw materials to prepare jute-based activated carbons by phosphoric acid activation and they are used as adsorbent.Methylene blue(MB) dye solutions which are widely used in textile printing and dyeing industry are chosen as adsorbate.Effects of various factors such as the initial concentration of the dye solutions,activated carbon dosage,adsorption time,water bath temperature and the pH value of dye solutions on the adsorption properties of jute-based activated carbon are investigated.Results show that with the initial concentration of the dye solutions increasing,the removal rate of the MB gradually reduces,while the adsorption amount gradually increases.However,with the increasing of activated carbon dosage,the adsorption time or the pH value of dye solution,both the removal rate and the adsorption mount of MB all increase gradually.Whereas,the effect of water bath temperature on the removal rate and the adsorption mount are not so obvious.The removal rate and the adsorption mount of jute stick activate carbon on MB are higher than that of jute fiber activate carbon due to lager specific surface area and pore volume.
