摘　　要：通过对三草酸合铁(Ⅲ)酸钾合成的实验条件进行优化,可在2 h内获得晶体产物。用KMnO4滴定法和磁化率测定方法,对产物结构组成进行测定,确定所合成的配合物化学式为K3[Fe(C2O4)3]·3H2O,有关测定数据与理论值相吻合。After the experimental conditions of synthesizing potassium ferrioxalate has been optimized, crystals can be obtained in 2 h. KMnO4 titration method and magnetic susceptibility analysis are adopted to measure the structure composition of the compound and confirm that its chemical formula is K3[Fe（C2O4）3]·3H2O. The actual results are identical with the theoretical figures.
