Abstract
A spectroscopic study of the reaction medium consisting of reverse AOT/water micelles in reverse water/AOT/heptane microemulsions, in which ZnS nanoparticles are synthesized in real time, was carried out. The synthesized nanoparticles were characterized using X-ray fluorescence analysis and UV absorption spectroscopy. The sensitivity of the Raman spectral characteristics to changes in the reaction medium parameters was found. Methods for remote express diagnostics of the reaction medium are proposed, allowing real time monitoring of the Na2S precursor concentration with an accuracy of 2.5% and determining the completeness of the ZnS nanoparticle synthesis stages by the intensity of the H–S stretching vibration band.
