GREEN SYNTHESIS OF ECO-FRIENDLY POTASSIUM NANOPARTICLES AND ITS APPLICATION IN AMARATHUS VIRIDIS, SOLANUM LYCOPERSOCUM AND HIBISCUS SABDARIFFA PLANTS

Abstract

Potassium Chloride and Polyalthia longifolia leaves extract were used for the synthesis of Eco-friendly Potassium Nanoparticles for application in Amarathus viridis, Solanum lycopersocum and Hibiscus sabdariffa. The synthesized Nanoparticles were characterized by scanning electron microscopy-energy dispersive X-ray (SEM-EDX) and Fourier transform infrared (FTIR). The SEM revealed a size range of 200nm with a near spherical shape synthesized Nanoparticles. Whereas EDX revealed an elemental composition of 19% Potassium, 4.46% Chlorine, 33.04% Carbon, 28.31% Oxygen and 14.30% Iron. FTIR revealed four distinctive  at 3235.3cm-1, 2109.7cm-1, 1640.0cm-1 and 1069.7cm-1 for Polyalthia longifolia potassium particles (Pl-KNPs). There were significant increase in all the folia applied Pl-KNPs when determined and compared with the controlled plants: Amaranthus viridis leaves recorded the highest increase with 56.81%, Solanum lycopersocum recorded the highest stem increase with 46.15%, while Hibiscus sabdariffa recorded the overall highest percentage with 224.27% attributed to its root length. This distinctive increase observed on the selected folia applied Pl-KNPs plants parameters is a confirmation of the significance of green synthesized potassium Nanoparticles in the field of agriculture.
