| Abstract: | The process of ferric ammonium EDTA production is improved for the agricultural application. The reactive mechanism, technological flow, procedure, optimum parameters and main technological indexes (Fe recovery>78%) are described. The final product of ferric ammonium EDTA is obtained with high Fe content (13.5%), good solubility and simple mixture. The experiment shows a positive effect for mixing the specialty compound fertilizer and coating. |
