摘 要: 采用固液相法制得乙二胺四乙酸铁钠,并用XRD、IR、DTA等对产物进行了表征,X射线粉末衍射数据指标化结果表明所合成的配合物属于单斜晶系,晶胞参数为:a=1.4388 nm,b=1.3521 nm,c=1.3311 nm,β=100.90°。同时确定了合成反应的较佳条件:n(EDTA)∶n[Fe(OH)3]=1∶1,pH=5,反应温度80°C,反应时间60 min,产率68.4%。 Sodium ethylenediaminetetracetato iron trihydrate was prepared by solid-liquid state reaction. The product was characterized by X-ray powder diffraction analysis, IR and DTA. The results of indexed X-ray powder diffraction data indicate that the crystal structure of the complex belongs to monoclinic system. The lattice parameters are:a=1.4388nm,b=1.3521nm,c=1.3311nm,β=100.90°. The optimum conditions for the preparation were found as follows: n(EDTA):n[Fe(OH)3]=1:1, pH=5, temperature of reaction 80℃, time of reaction 60 min. The yield was 68.4%.
