活性碳纤维是一种高效吸附新型功能材料,具有巨大的比表面积、均匀的微孔和丰富的表面基团,以及大的吸附容量和吸附速率,已被广泛应用于气体净化、废水处理中。我们于70年代率先在国内开展了活性碳纤维的研究,80年代首先发现了其氧化还原特性,开拓了活性碳纤维提取贵金属方面的应用。活性碳纤维吸附提取贵金属具有可以吸附很低浓度的金银离子、选择性高、其它金属离子影响小、环境污染小等优点,有广泛的应用前景。 本项目在原有工作基础上研制开发新型活性碳纤维,探索提高这些新型功能纤维还原能力、实现功能纤维还原提取回收金
Activated carbon fiber is a kind of new functional material with high efficiency adsorption. It has huge specific surface area, uniform micropore and abundant surface groups, as well as large adsorption capacity and adsorption rate. It has been widely used in gas purification and wastewater treatment. We took the lead in the 70’s in the domestic activated carbon fiber research, first discovered in the 80’s redox properties, opened up the use of activated carbon fiber extraction of precious metals. Activated carbon fiber adsorption extraction of precious metals has a low concentration of gold and silver ions can be adsorbed, high selectivity, the other small metal ions, environmental pollution, etc., has a wide range of applications. The project on the basis of the original work on the development of new activated carbon fiber, to explore and improve these new functional fiber reducing ability to achieve recovery of functional fiber recovery gold
