Research and Possible Agronomic Applications of C60(OH)24 Adducts with Heavy Metals for Crop Treatment

Abstract

This article describes the synthesis of fullerenol—C60(OH)24 adducts with some heavy metals—C60(ONa)x(O2Me)(24−x)/2;C60(ONa)x(O3Me)(24−x)/3; Me=Co; Cu; Mn; Zn; Gd; Tb. The identification of adducts was carried out by the methods of: elemental analysis, infrared and electronic spectroscopy, complex thermal analysis, high-performance liquid chromatography and dynamic light scattering. The solubility of adducts in aqueous solutions in the ambient temperature range has been studied. The solubility was significant and ranged from a few tenths to 1 g/dm3. The use of these adducts as micronutrients for spring barley crops in the Republic of Kazakhstan is considered. When using these nanopreparations, a general increase in yield (tens, up to 80 rel.%), nutrient content and moisture content of seeds (4–5 rel. mass %), as well as the resistance of the latter to the effects of pathogenic microorganisms (percentage of healthy seeds growth up to 10 rel.%), was noted.
