中文摘要:

almond-shell-based 的烟碱吸附能力上的微观结构和表面化学的效果激活碳被学习。Almond-shell-based 激活碳独立与蒸气, ZnCl2 和 NaHSO4 被重新激活或修改。激活的碳的表面区域和毛孔结构参数在 77 K 从氮的吸附解吸附作用等温线被决定。Boehm 滴定和 FTIR 被探索决定表面氧组。结果表明从碳上的答案的烟碱吸附取决于 micropores 和酉分的组。在吸附的烟碱和酉分的组的数量之间的强壮的关联被观察,而羧基的组的更高的数量减少激活的碳上的烟碱吸附能力。

英文摘要:

The effect of microstructure and surface chemistry on nicotine adsorption capacity of almond-shell-based activated carbon was studied. Almond-shell-based activated carbon was reactivated or modified with steam, ZnCl2 and NaHSO4 separately. The surface area and pore structure parameters of activated carbon were determined from the adsorption-desorption isotherm of nitrogen at 77 K. Boehm titration and FTIR were explored to determine the surface oxygen groups. The results revealed that nicotine adsorption from solution on carbons depend on the micropores and phenolic groups. A strong correlation between the amounts of adsorbed nicotine and the phenolic groups was observed, whereas the higher amounts of carboxylic groups decrease the nicotine adsorption capacity on activated carbons.
