| Resumo: | Selenium-containing nanoscale systems stabilized with alkyldimethylamine oxide are obtained. Based on computer quantum-chemical modeling, it is established that alkyldimethylamine oxide is the optimal stabilizer. During optimization of the synthesis technique, the optimal concentrations of the components are established: C (selenous acid) = 0.3536 mol/L, C (alkyldimethylamine oxide) = 0.0339 mol/L, C (ascorbic acid) = 0.0992 mol/L. This sample is examined using the transmission-electron-microscopy method. The stability of the sample is established in the concentration range of NaCl, BaCl2, and FeCl3 salts up to 0.5 mol/L, and Na2SO4 and K3PO4 salts up to 0.1 mol/L, as well as in the pH range from 8 to 12. |
