摘要/Abstract

摘要： 为了提高活性炭纤维(ACF)对水体中磷的吸附性能，采用硫酸亚铁溶液对其进行改性，并用正交实验法分析得到最佳改性条件为：pH值为3，FeSO₄·7H₂O的质量浓度为100kg/m³，FeSO₄·7H₂O和ACF的质量比为2.5，反应时间3h.将改性后的ACF对模拟含磷废水进行静态吸附，测定了吸附等温线，研究了吸附时间、投加量、pH值对处理效果的影响，实验结果表明，改性后ACF对磷的吸附效果较好，去除率可以达到99%.

Abstract: An activated carbon fiber (ACF) was placed in a solution of ferrous sulfate at different conditions to improve its adsorption capacity. The primary factors affecting phosphorus adsorption on a modified ACF were analyzed by the orthogonal experimental method. The best modifying conditions are that pH value is 3, the concentration of FeSO₄·7H₂O is 100kg/m³, the m(FeSO₄·7H₂O)/m(ACF)=2.5, and time of stirring is 3 hours. The modified activated carbon fiber was used to study static adsorption of phosphoruscontaining wastewater and the adsorption isotherm was determined. The effects of factors such as adsorption time, the amounts of ACF and the pH on adsorption efficiency were studied. Experimental results show that a modified ACF effectively removes phosphorus.

Key words: modified activated carbon fiber, orthogonal experimental, phosphorus removal
