Abstract: (1185 Views)
Due to the need for safe water, it is important to identify water contaminants, Contaminants caused by metal ions are one of the types that threaten human health and living organisms. In this paper, the plasmonic effect of gold nanoparticles on the detection of copper heavy metal ions, one of the most important contaminants in drinking water, is investigated. Gold nanoparticles were prepared by vapor phase deposition method and complementary process and FESEM imaging confirmed the presence of 20-50 nm nanoparticles. In a fluidic system, the presence or absence of a fluid containing copper ions was investigated by ultraviolet-visible spectroscopy. The study confirmed the plasmonic peak change of gold nanoparticles and the refractive index of the presence of copper ions at concentrations greater than 1 ppm.
