A highly sensitive and selective resonance Rayleigh scattering method for Hg2+ based on the nanocatalytic amplification
In 0.2 mol/L HCl–0.22 mol/L HNO3 medium, trace Hg2+ catalyzed NaH2PO2 reduction of HAuCl4 to form gold nanoparticles (AuNPs), which exhibited a strong resonance Rayleigh scattering (RRS) effect at 370 nm. With increasing of [Hg2+], the RRS effect enhanced due to more AuNP generated from the catalyti...
