响应曲面法优化活性炭纤维吸附性能研究

Optimization of Adsorption Properties of Activated Carbon Fibers by Response Surface Methodology

利用响应曲面法对提高活性炭纤维吸附能力的主要因素包括辐射剂量、单体浓度、反应温度进行试验设计。以活性炭纤维的苯酚吸附量为响应函数,建立相应的数学模型,优化试验方法。得到活性炭纤维的苯酚吸附量为最大时的最佳试验条件为:辐射剂量为49.33 KGy,单体浓度为10.26%,反应温度为84.52℃。结果表明,响应曲面法用于优化筛选提高活性炭纤维吸附能力的影响因素是可行的,且数学模型的预测值与试验观察值相符。

The response surface methodology was used to design the main factors to improve the adsorption capacity of activated carbon fiber, including radiation dose, monomer concentration and reaction temperature. The corresponding mathematical model was established based on the phenol adsorption capacity of activated carbon fiber. The optimal experimental conditions for the adsorption of＂ activated carbon fiber was 49.33 KGy, the monomer concentration was about 10.26%, and the reaction temperature was about. The results show that the response surface method is feasible to optimize the screening and improving the adsorption capacity of activated carbon fiber.
