Improvement of Preparation and Property Experiment of Ferric Hydroxide Colloid

针对现行的物理化学实验中的溶胶电泳实验,胶溶法存在容易失败的问题,水解法存在渗析纯化所需时间过长的问题,采用用盐酸溶液作为胶溶法的分散剂,对Fe（OH）3胶体实验进行了改进,省时简便,成功率高,可不经过渗析直接进行电泳实验。

In traditional physical chemistry experiment of ferric hydroxide colloid electrophoresis,colloidal chemical method often ends up in failure,and hydrolysis method is time consuming in dialysis and purification.This article put forward a new simple and efficient method for preparation and electrophoresis of ferric hydroxide colloids,in which hydrochloric acid solution was used as dispersant in preparation and electrophoresis experiment could be performed without dialysis.
