富里酸络氨铜的合成与表征
|
摘要
针对富里酸在农业上的重要作用,合成一种兼具富里酸和铜离子优点的富里酸络氨铜(FA-Cu),将其应用到农作物肥料中,达到绿色环保、低成本的优点。本文采用单因素和正交试验的方法,研究了pH值、富里酸浓度、硫酸铜浓度等因素对合成富里酸络氨铜的质量、纯度、颗粒均匀程度的影响。结果表明:富里酸浓度为3%,硫酸铜浓度为4%,pH值为7时为最佳合成条件,此条件下合成的富里酸络氨铜沉淀颗粒体积较小、分布均匀、没有团簇现象,并通过红外光谱分析和热重分析对产物进行了表征,分析结果表明合成了富里酸络氨铜。
In view of the important role of fulvic acid in agriculture, it is required to synthesize a fulvic acid complex ammonia copper(FA-Cu) with the advantages of fulvic acid and copper ions, which can be applied to fertilizers to achieve the advantages of environmental protection and low cost. In this paper, the factors of pH, fulvic acid concentration and copper sulfate concentration were studied by single factor and orthogonal methods in order to examine it's effect on the quality, purity and particle uniformity of the fulvic acid complex ammonia copper.The results show that the concentration of fulvic acid of 3%, the concentration of copper sulfate of 4%, and the pH=7 is the best synthesis condition. Under this condition,the particles of fulvic acid complex ammonia copper are smaller, evenly distributed, and have no clusters. The product was characterized by infrared spectroscopy and thermogravimetric analysis. The analysis results show that the FA-Cu was synthesized.
