This work reports the preparation and characterisation of silver nanoparticles (AgNPs) through chemical reduction method with three different procedures denote as modified Mulfinger’s Method, Mulfinger’s Method and Malina’s Method. The yellow colloidal solution were characterised and analysed using Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive X-ray Spectroscopy (EDS), X-Ray Diffraction (XRD). FESEM and EDS analyses confirmed that the formation of AgNPs in Malina’s Method with highest yield of silver (Ag), 67.39 % weight as compared to Mulfinger’s and modified Mulfinger’s Method. The peaks in XRD pattern for Malina’s Method are in good agreement with face-centered-cubic form of metallic silver while modified Mulfinger’s Method and Mulfinger’s Method XRD pattern suggest the halite/sodium chlorate and silver chlorate peaks respectively. Malina’s Method is found to be a suitable method to study AgNPs.
