Metal citrate nanoparticles: a robust water-soluble plant micronutrient source.

ABSTRACT: A series of iron (Fe) and zinc (Zn) plant nanonutrients in citrate form were prepared by an eco-friendly solid-state grinding of the respective nitrates and citric acid. Ball-milling of the as-prepared Fe and Zn citrates resulted in nanosize particles. The as-prepared and ball-milled Fe and Zn citrates were characterized using Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis and differential thermal analysis (TGA/DTA), and powder X-ray diffraction (XRD). The particle size and morphology of the obtained samples were studied using a scanning electron microscope (SEM) and transmission electron microscope (TEM). The obtained nanosized Fe and Zn citrates were analyzed for their plant uptake in the test crop soybean (var. JS-335) using the white-sand technique. The conc
