活性炭纤维对稀土离子Ce3+吸附性能的研究
dsorption of Ce3+ by using active carbon fiber
通过活性炭纤维对稀土Ce3+的吸附实验，研究活性炭对Ce3+的吸附性能。探讨在静态条件下，活性炭纤维的用量，标准溶液的浓度，吸附时间，体系的温度等条件对活性炭纤维吸附性能的影响；测定Ce3+的吸附等温线，采用Langmuir和Freundlich模式对吸附平衡实验数据作了线性模拟，对吸附等温线进行探讨。 结果表明，活性炭纤维对Ce3+有较强的吸附性，最高吸附率可达95%以上。在所选的条件范围内，标准溶液的最佳初始质量浓度为1.5 g/L，活性炭纤维最佳质量为0.12 g，最佳吸附时间50 min，体系的最佳温度为298 K。
he adsorption capability of the activated cabon fiber(ACF) was studied by the experiment of adsorbing Ce3+. The influenced condition, such as dosage of ACF, original sulution concentration, adsorption time, system temperature, was investigated in still state. The results showed that the optimal conditions were Ce3+ original concentration 1.5 g/L, dosage of ACF 0.12 g,adsorption time 50 min and system temperature 298 K. Under the optimal conditions, the best adsorption rate can reach 95 % above.
