In this work, FTIR spectrometry was used to analyse the spectra configurations on the synthesised silver nanoparticles were synthesized using two different reducing agents (1) sodium borohydride (NaBH4), at two temperature conditions of 27⁰C and 4⁰C (room temperature and ice cold temperature), and (2) trisodium citrate (3NaCi) at 100⁰C (boiling temperature) by chemical reduction method.
The resulting nano-sized colloids have been characterized by FTIR spectroscopy. A clear and yellow colouration was obtained from all the synthesised samples, which indicates the presence of formed nanoparticles with strong absorption peaks obtained at wave length range of 1370 - 1380 cm-1 and 840 - 841 cm-1proving the presence of silver nanoparticles based on the functional group. The elements found to be present at such peak were the nitro and N-O functional groups.
