Selective resonance Rayleigh scattering spectroscopic determination of persulfate using cetyl trimethylammonium bromide capped cuo nanograins

Abstract

The authors were able successfully to produce uniform copper oxide nanograins (CuO NGs) using cetyl trimethylammonium bromide as capping agent. These nanograins were developed to design a new nanoprobe that will be able to determine persulfate anions in water sample based on Resonance Rayleigh Scattering (RRS) Technique. CuO NGs nanosensor were found to be selective for the detection of persulfate anions in the concentration range of 1–100 μM with a detection limit equal to 1.03 μM. The synthesized CuO NGs were sensitive towards the detection of persulfate anions and gave a recovery percentage between 98–100%. © 2020 Elsevier B.V.
