针对无机化学综合实验三草酸合铁(Ⅲ)酸钾合成过程中存在的问题,对[K3Fe(C2O4)3].3H2O的合成条件进行探索和优化.实验结果表明:在用热水(40℃)洗涤FeC2O4,40℃时逐滴加入H2O2后煮沸30s,利用浓缩后挂棉线的方式进行结晶等条件下,得到粒度较大的翠绿色晶体,可改善实验结果的重现性、提高产品的产率和纯度.
針對無機化學綜閤實驗三草痠閤鐵(Ⅲ)痠鉀閤成過程中存在的問題,對[K3Fe(C2O4)3].3H2O的閤成條件進行探索和優化.實驗結果錶明:在用熱水(40℃)洗滌FeC2O4,40℃時逐滴加入H2O2後煮沸30s,利用濃縮後掛棉線的方式進行結晶等條件下,得到粒度較大的翠綠色晶體,可改善實驗結果的重現性、提高產品的產率和純度.

Aiming at the previous problems, it tries to optimize conditions of the formation for Potassium tris(oxalato)ferrate(lll) trihydrate. The experimental results show that, FeC2O4 washed with hot water, when the water tempreture is 40℃, H2O2 is added into the water drop by drop, then it must be boiled for 30s. After consentration, it is crystalized and bigger viridis crystals are gotten. Meanwhile, repeatability of experimental result is improved, productivity and purity of the products are enhanced.
