Abstract

In the purification treatment of printing and dyeing wastewater, the addition of nanoparticles can promote energy absorption and regulate evaporation processes through spectral property modulation. To clarify the influences of nanoparticle structure and material on the regulation of spectral properties, nanoparticle models with standard sphere, rough sphere and double-layer core-shell structure are established in this paper. The materials of nanoparticles are silver and silicon, respectively. The scattering and absorption properties in the wavelength band of 200nm-2000nm are calculated by the FDTD method and analyzed. The results show that the surface roughness of nanoparticle has little effect on spectral properties, and the variation of the particle diameter has a larger effect on the scattering factor. Comparing with the single-component nanoparticle, the core-shell structure composing two materials has better ability to regulate the spectral properties.
