铁(Ⅱ)与尿素配合物的制备方法

Study on the Fe^(2+) Complex

用硫酸亚铁与尿素反应合成了尿素铁(Ⅱ)晶体络合物,易溶于水,在空气中稳定,吸湿性小.红外光谱提示,二价铁与尿素中的氮原子发生了络合,使金属更易被植物吸收,使氮缓释,因而合成的络合物不仅是优良的配合型微量元素肥料,而且也是常效氮肥.

In this paper, a kind of crystal complex is synthesized using FeSO4 and N2H4CO,which dissolves water,stabilizes in air . and whose hygroscopic is little. The infrared spectrum of this complex indicates that Nitrogen atoms in the N2H4CO are coordinated with Fe^2＋ ,which can help plants absorb the metallic iron and induce the delution of the Nitrogen . Therefore, this complex is not only excellent microelement but also common nitrogenous fertilizer.
