In 6 mol/L HCl medium, NaH2PO2reduced HAuCl4to generate gold nanoparticles (AuNPs). AuNPs have a strong resonance Rayleigh scattering (RRS) peak at 369 nm. As HAuCl4concentration increases in 0.04-0.8 mmol/L, the AuNPs generated increase, and the RRS peak ΔI369nmenhanced linearly, the linear regression equation wasΔI369nm= 5122CAu+13.2, linear correlation coefficient was 0.9968. This method has the advantages of high sensitivity, good selectivity, easy to operate.
