Effect of Dyes on Resonance Scattering Spectrum of S Ultrafine Particles
Abstract:
In presence of polyacrylamide (PAM) sulfur nanoparticle solutions have a maximum resonance scattering peak at 470 nm,but no absorption peak appears in visible light region.The mass concentration of sulfur particles in the range of 0.05~1.0 mg/L is linear to the resonance scattering intensity at 470 nm.The effects of dyes such as bromophenol blue (BPB),bromomethyl violet (BMV),crystal violet (CV) and brilliant green (BG),and some organic solvents such as acetone,alcohol and methanol on the resonance scattering spectra of S nanoparticle have been studied.It is found that the molecular absorption of the dyes is an important factor to produce scattering peak,and the resonance scattering intensity decreases exponentially with the concentration of the dye.At maximum absorption wavelength of 590 nm,the concentration of BPB is linear to the ΔI590 nm value in the range of 0~1.0×10-5 mol/L.
