In lab oratory experiment, zinc nano fertilizer (ZnO NPs) was synthesized, using direct precipitation method and cha racterized by Dynamic Light Scattering (DLS), Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR) analysis. Th e i nstrumental analysis results indicated that synthesized ZnO NPs were of 35 40 nm particle size , monodispersed, pure, stable and showed characteristic absorption of Zn O bond at wavenumber of 509.46 cm 1 and 604.70 cm 1EnglishThesis
