| 摘 要： | 研究了以天然纤维制备新型的活性碳纤维(SACF)的制备条件以及 SACF 对水溶液中金属离子的吸附性能。实验结果表明,活化反应条件如反应温度、时间、活化剂流速等对 SACF 的比表面积有较大的影响。SACF 对水溶液中的La~(+++),Cu~(++),Co~(++),Ni~(++),Cd~(++),Pb~(++)等离子基本上不吸附,而对贵金属 Au~(+++)具有吸附率高、吸附选择性好、吸附速度快、吸附量大等优异性能。

| Abstract: | The preparation conditions of activate carbon fiber SCAF,which are madeof natural fiber,and adsorptive properties towards metal ions in the aqueous solution havebeen investigated.The experimental results indicated that condition of activated reactionsuch as reaction temperature,reaction time and rate of feeding of activation agent influencesignificantly on the surface area of SACF.SACF is a very good adsorbent for preciousmetal ions such as Au~(3+) in the aqueous solution. |

| Keywords: | activated carbon fiber specific surface area adsorbent precious metal ions |
