ABSTRACT

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.
