Аннотация: We examined the interaction of aqueous solutions of lead nitrate and sodium dibutyl dithiophosphate and showed the formation nanoparticles of lead dibutyl dithiophosphate. The effect of reaction parameters on the synthesis of nanoparticles was studied and the optimal conditions for the formation of their stable hydrosols were deterПоказать полностьюmined. The obtained products were investigated by methods of optical spectroscopy, dynamic light scattering. The average size of 15-20 nm, but due to the low surface charge, they are combined into larger aggregates. The UV-vis spectra has absorption maximum at about 320 nm. TEM micrographs and Pb 2p, S2p XAS spectra revealed a composition and structure of the particles. These nanoparticles can play an important role in the flotation of sulfide minerals of nonferrous metals.
