ABSTRACT

Copper nanoparticles were synthesized using green tea (Camellia sinensis ) extracts and the application were channelled towards the sensing of heavy metals. The synthesized green tea copper nanoparticles were characterized using Fourier transform infrared spectroscopy, UV/visible spectroscopy, thermal analysis and powder x-ray diffraction techniques, the results from the UV-visible spectroscopy reveals the existence of localised surface plasmon resonance appeared at 400nm, the synthesized copper nanoparticles exhibit Face centred cubic structure of Copper nanoparticles a (JCPDS-04-0836 )s indicated by the powder X-ray diffraction techniques the detection of silver and gold by green tea copper nanoparticles shows a bathochromic shift towards the heavy metals sensed.
