Research and Possible Agronomic Applications of C 60 (OH) 24 Adducts with Heavy Metals for Crop Treatment.

This article describes the synthesis of fullerenol— C 60 (O H) 24 adducts with some heavy metals— C 60 (O N a) x (O 2 M e) (24 − x) / 2 ; C 60 (O N a) x (O 3 M e) (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.
