摘　　要：在大学生本科无机化学实验中,三草酸合铁(Ⅲ)酸钾的合成及光致还原性实验是一个典型的综合性的实验。目前现有的制备方法大多存有原料易潮解、操作繁杂、制备时间长、产率低等缺点。本实验在已知的制备方法的基础上对原料的选取、反应过程的控制、产品的纯化结晶三个阶段进行了创新设计。该改进实验过程更易控制、析出时间更短,产率更高,现象明显。In the undergraduate Inorganic Chemistry experiment,the synthesis and photosynthetic reduction experiment of potassium iron(III)is a typical comprehensive experiment.Most of the existing preparation methods have some disadvantages,such as easy deliquescence of raw materials,complicated operation,long preparation time and low yield.The innovative design was carried out in the three stages of raw material,reaction and treatment,and the experimental process was easier to control,the precipitation time was shorter,and the yield was higher.
