间歇式转化研究表明，玉米芯可以有效地去除水溶液中的六价铬。这个过程非常依赖pH值，pH值为1时效果最好。转化的机理有还原和吸附两种，吸附是反应的限制步骤。本文提出的模型似乎能很好地模拟实验数据。
Batch conversion studies have shown that corncob can be used effectively to get rid of hexavalent chromium from aqueous solutions. The process is very pH dependant, a pH of 1 giving the best results. The mechanisms involved in the conversion are reduction and adsorption, the first one being the limiting step of the reaction. A model is proposed which seems to simulate the experimental data quite well.
