摘　　要：对三草酸合铁(Ⅲ)酸钾合成的实验条件进行了优化,可在2个小时内获得晶体产物,仅为常规方法的一半时间.采用了化学分析、热重分析、红外光谱分析等方法,准确测定晶体产物的组成与结构,实验得到的有关测定数据与理论值相吻合.这些测试方法与测试结果又可为学生的实验结果的表征提供了重要的参考信息.The experimental conditions of synthesizing potassium ferrioxalate were optimized to obtain crystals in 2 hours, saving half of the time compared with conventional method. The paper adopted chemical a- nalysis, thermogravimetric analysis and infrared spectrum analysis to accurately measure the structure and compo- sition of crystals. The results are identical with the theoretical figures. The testing methods and results can pro- vide important reference for the representable features of testing results obtained by students.
