双酚A是一种典型的环境激素，广泛存在于人类的生活之中，对人类的生活有着极其深远的影响。本文通过GAC、CAC和PAC 3种活性炭分别吸附双酚A的行为分析，考察活性炭对双酚A的吸附能力。用一级动力学方程、二级动力学方程、Elovich方程、双常数方程和扩散方程对实验数据进行拟合，选择实验平衡浓度较理论平衡浓度的差异来评价模型拟合度，得出二级动力学方程能够很好地描述3种活性炭吸附双酚A的行为。此外，Elovich方程的拟合效果也比较理想，说明吸附过程为先快吸附后慢吸附，得出吸附双酚A的能力为：CAC＞PAC＞GAC。

BPA is one kind of typical environmental hormone ,widely existed in human life and deeply affecting human life . In this study ,BPA is absorbed by three kinds of activated carbons (granular ,cylindrical and powder) in order to investigate the adsorption capacity of activated carbon on BPA and to analyze the kinetic parameters by batch adsorption studies .Equi-librium data is analyzed by the first-order kinetic model ,second-order kinetic model ,Elovich equation ,two-constant equation and parabolic diffusion equation .It is selected the difference between the experimental equation concentration and the theoretical equation concentration to evaluate the model fitting and it is found that the second-order kinetic model can well describe the adsorption behaviors of three kinds of activated carbon on Bisphenol A .Furthermore Elovich equation is al-so ideal in fitting ,indicating that the main behavior is divided into two stages ,fast adsorption and slow balance and the ad-sorption order follows CAC>PAC>GAC .
