The effect of coupling alternating current (AC) with biosorption using Tunisian corn stigmata on the removal of hexavalent chromium (Cr(VI)) from aqueous solution was studied. A comparative study was performed between biosorption alone and biosorption coupled with AC, for the removal of Cr(VI). The effects of various operating parameters were studied, such as the solution pH, the contact time, the initial concentration, the temperature, and the salt concentration. The comparison between biosorption in the presence and absence of an AC shows the importance of the AC in the acceleration of the biosorption process. The kinetic study showed that the fractal Brouers‐Sotolongo model was the best model for describing the random distribution of the active sites.

交流电和生物吸附耦合去除六价铬

研究了使用突尼斯玉米柱头将交流电（AC）与生物吸附耦合对从水溶液中去除六价铬（Cr（VI））的影响。在单独的生物吸附与结合AC的生物吸附之间进行了比较研究，以去除Cr（VI）。研究了各种操作参数的影响，例如溶液的pH值，接触时间，初始浓度，温度和盐浓度。在存在和不存在AC的情况下生物吸附之间的比较表明AC在加速生物吸附过程中的重要性。动力学研究表明，分形的Brouers-Sotolongo模型是描述活性位点随机分布的最佳模型。
