Abstract

The results of the synthesis and spectroscopic study of the photocatalytic activity of water-soluble arabinogalactan-stabilized zinc oxide nanoparticles are presented. Thanks to the stabilizing ability of the natural polysaccharide arabinogalactan, a composite containing 1.2% ZnO nanoparticles measuring 1–4 nm is obtained for the first time. The photocatalytic activity of the obtained composite in the process of ultraviolet-induced decomposition of the systemic herbicide clopyralid is studied using spectroscopic methods. It is found that this activity directly depends on both the type of radiation (visible/UV) and the concentration of aqueous solutions of the composite.
