摘　　要：为改进电泳实验使之更适合本科实验教学,采用了渗析法和络合法处理氢氧化铁溶胶,分别作电泳实验,测量出电泳速率并计算出电势值。实验结果表明：用渗析法对氢氧化铁溶胶进行净化后得到的电势值在43~48 mV之间,采用此方法得出的数据较准确并且重现性好;采用尿素对氢氧化铁溶胶络合法处理后得到的电势值在32~47 mV之间,该方法操作简单快捷而且实验成功率较高。由此说明这两种方法对实验结果的影响均不大,因此采用尿素络合法更适合学生做实验。In order to improve electrophoresis test for the undergraduate,the electrophoresis rates are measured and its potential values are calculated by methods of dialysis and complex for ferric hydroxide solvent respectively.The experiment results indicate that Potentials values are obtained between 43 ~ 48 mV after purification for the ferric hydroxide solvent by the dialysis method,which are more accurate and repeatable,potentials values are obtained between 32 ~ 47 mV after the complex method for the ferric hydroxide solvent with urea,this method is simple and also higher chance of success.It shows that the two methods on the experimental results have little difference.Therefore,the complex transacting with urea is more suitable for students.
