摘要：

XPS investigations of the sorption of methyl, ethyl and amyl xanthates at the surface of lead sulfide and galena, with special attention for the submonolayer region, are described. Lead xanthate in the molecular form as the adsorbing entity is proposed on the basis of the analysis of XPS spectra of the surface after sorption. The uneven distribution of xanthate at the surface, even at low surface coverage, is suggested.
