Abstract

The production of the Zinc oxide nanoparticles through aqueous stem extract of Anthocephalus cadamba Lin is performed. The formed nanoparticles tested for the toxic chromium metal removal activity, germination, and growth supporting of green gram seeds. The NPs were portrayed by FTIR, X-ray Diffraction, SEM, and EDX studies and confirmed irregular and complex structures. The % Chromium metal reduction of 87.83 %, 65.83 %, 48.00 % and 38.67 % was calculated at nanoparticle dosage of 1, 0.5, 0.25 and 0.10 g/L respectively. The amount of zinc accumulation in the roots of green gram was studied. The amount of Zn in the root tissue was increased significantly with the synthesized nanoparticles than zinc sulfate. It was observed that soil having ZnO-NPs shows the utmost rate of germination, root, and plant growth than with control and zinc sulfate.
