Abstract

Abstract
Due to the destructive effects of heavy metal ions on human health, providing a simple and inexpensive way to detect and measure them in an aquatic environment is one of the important research areas. In the present work, a simple optical sensor based on gold nanoparticles with chitosan was introduced to detect and measure heavy metal ions in water. These metal ions result in the accumulation of gold-chitosan nanoparticles through the chelating reaction between chitosans and metal ions. The sensitivity of the sensor was investigated for Cu2+, Ni2+, Pb2+, Cd2+ and Hg2+ ions. The results showed that different metal ions cause a different reduction in the plasmon bar. The detection limit for each copper, nickel, lead, cobalt, cadmium and mercury ions was 2.48, 0.27, 0.25, 0.40, 0.28 and 1.43, respectively. This optical sensor showed the most sensitivity to Pb2+ ions. According to the results, this sensor can successfully be used to detect heavy metal ions in water and wastewater samples.
