水热法或水热修饰法合成功能性碳材料与其在吸附分离方面的应用摘 要传统的吸附材料，如活性炭、离子交换树脂等，在对溶液中重金属离子的吸附过程中，具有选择性差、条件要求苛刻等缺点。本课题以葡萄糖为碳源，以含有巯基、羧基或者氨基的氨基酸或化合物(如巯基乙酸)为添加剂，在 180℃下，通过一步水热碳化法，合成出一种新型功能性碳材料，其对重金属离子的吸附效果优于传统的碳材料。并且本方法制备出的碳附材料表面酸量和硫含量可以调控。关键词：水热碳化，碳材料，巯基乙酸，吸附，可控AbstractThe traditional adsorption materials, such as activated carbons and ion exchange resins, have shown the drawbacks of poor selectivity and low capacity . Here, we adopted facile method for one-step synthesis of new functional carbon spheres by HTC of the mixture of mercaptoacetic acid and glucose at 180 °C. Compared to the traditional carbon materials, it shows excellent heavy metal removal performance. In addition, we can tailor the amount of sulfur and surface acid of the material.Keywords:hydrothermal-carbonization, carbon material, mercaptoaceticacid, adsorption, controllable目录1 文献综述11.1 讨论背景...........................................................11.2 碳材料.............................................................21.3 多孔碳材料的合成方法...............................................21.4 碳材料的表面修饰...................................................51.5 水热碳化法.........................................................71.6 吸附..............................................................131.7 本课题的讨论背景与主要工作内容....................................152 实验方法 172.1 实验仪器与试剂....................................................172.2 碳材料的合成......................................................182.3 吸附试验..........................................................182.4 材料的表征方法....................................................183 结果与讨论 243.1 SEM 图...
