Fi-Ir and FT-Raman Studies of Colloidal ZnS .1. Acidic and Alkaline Sites at the ZnS Water Interface
The surface complexes of colloidal ZnS have been studied using FT-IR and FT-Raman techniques. The absorption bands at 2500 and 1475-1375 cm(-1), which are identified as the S-H bond and the Zn-OHCO2 entity, respectively, can be observed under varied conditions of sample stoichiometry and pH. The correlation between surface spectra and the complexation model is evaluated. The relation between the intensities of FT-IR and FT-Raman spectra and particle size is discussed.
