玉米麸质铁对六价铬有较好的吸附能力,吸附等温式符合Langmuir公式:吸附动力学特性可以用下式描述:扩散活化能为21.85KJ/moL,表明吸附过程受颗枉扩散控制。
Corn bran iron has good adsorption capacity for hexavalent chromium. The adsorption isotherm follows the Langmuir equation. The adsorption kinetics can be described by the following equation: The diffusion activation energy is 21.85 KJ / mol, which indicates that the adsorption process is controlled by diffusion.
