  • 摘要: 以葡萄糖为前驱物，以氨水或谷氨酸为添加物，通过一步水热法制备出氨基功能化碳材料，并研究了这些碳材料对活性艳红K-2BP的吸附性能。结果表明，在葡萄糖水热过程中加入不同添加物可以得到不同形貌的碳材料（从微球到不规则形状）。当以只有葡萄糖为前驱物制备的碳微球作为K-2BP的吸附剂时，其对K-2BP的最大吸附量为6.28 mg/g。当在水热体系中加入氨水和谷氨酸作为共聚物后，两者会产生协同作用，使得到的碳材料对K-2BP的吸附性能大大提高，最大吸附量达到37.0 mg/g。单纯的葡萄糖水热体系得到的碳微球对K-2BP的吸附符合Langmuir吸附等温线，而氨基功能化的碳材料对K-2BP的吸附符合Freundlich吸附等温式，吸附过程符合准一级动力学模型。低的溶液pH有利于K-2BP的吸附。
    Abstract: Amino-functionalized carbon materials were prepared by one-step hydrothermal carbonization of glucose with ammonia water and glutamic acid as co-monomer,and their adsorption behavior for a dye reactive brilliant red K-2BP was studied.The results show that the morphology of the obtained carbon materials depended on the additives.The adsorption capacity of K-2BP on carbon material from the hydrothermal carbonization of glucose in the absence of additive was 6.28 mg/g,while the adsorption capacity of K-2BP on the carbon material obtained from that with ammonia water and glutamic acid as co-monomers increased significantly to 37.0 mg/g.The adsorption process of K-2BP on the carbon material prepared from the hydrothermal carbonization of glucose in the absence of additive could be described by the Langmuir isotherm model,while that by the amino-functionalized carbon materials could be described by the Freundlich model,and the adsorption kinetics followed the pseudo-first-order kinetics model.Low pH value favored the adsorption of K-2BP.
