The composition and hydrodynamic diameter of reverse micelles Me(AOT)_n (n = 1–3) were determined during injection solubilization of nitrate salts of Li⁺, Na⁺, K⁺, Cs⁺, NH₄⁺, Ag⁺, Ni²⁺, Co²⁺, Zn²⁺, Cu²⁺, Cd²⁺, Ca²⁺, Al³⁺, Fe³⁺, and La³⁺ cations and upon solvent extraction from their concentrated (1‒2 mol/L) solutions. It was found that solvent extraction by NaAOT reverse micelles can increase the concentration of cations in microemulsion by a factor of 10‒20 as compared to injection solubilization. Therewith, the fraction of super equivalent extraction of cations as nitrate salts into the aqueous cores of reverse micelles can reach 150%. According to the study, the higher is the hydration energy of cation, the greater is the number of successive extraction steps (up to 4) required for a virtually complete (more than 99%) replacement of Na⁺ in AOT micelles. The hydrodynamic diameter of Мe(AOT)_n micelles was in the range from 3.2 to 13.9 nm, and the content of aqueous pseudophase, from 1.2 to 10.4 vol.%. It was demonstrated that the obtained extracts could be used for enhancing the productivity of micellar synthesis of nanoparticles (Ag and CdS) and isothermal micellar crystallization of salts (LiNO₃, KNO₃, CsNO₃), and also as the charging agents (Cu(AOT)₂, Ni(AOT)₂, and Fe(АОТ)₃) of SiO₂ nanoparticles in the n-hexadecane-chloroform mixture.

在注入溶解Li ⁺，Na ⁺，K ⁺，Cs ⁺，NH ₄ ⁺，Ag ⁺，Ni ²的硝酸盐的过程中，确定了反胶束Me（AOT）_n（n = 1-3）的组成和流体动力学直径。⁺，Co 2 ⁺，Zn 2 ⁺，Cu 2 ⁺，Cd 2 ⁺，Ca 2 ⁺，Al ³⁺，Fe ³⁺和La ³⁺阳离子，并从浓溶液（1‒2 mol / L）中萃取溶剂。研究发现，与注射增溶相比，NaAOT反胶束萃取溶剂可使微乳液中阳离子的浓度增加10‒20。从而，将阳离子作为硝酸盐的超当量萃取到反胶束的水芯中的比例可达到150％。根据研究，阳离子的水合能量越高，AOT胶束中Na ⁺的几乎完全替代（超过99％）所需的连续萃取步骤（最多4个）的数量就越大。Мe（AOT）_n的流体力学直径胶束的范围为3.2至13.9nm，假水相的含量为1.2至10.4vol。％。结果表明，所得提取物可用于提高纳米颗粒（Ag和CdS）的胶束合成的生产率以及盐（LiNO ₃，KNO ₃，CsNO ₃）的等温胶束结晶，还可以用作荷电剂（Cu（正十六烷-氯仿混合物中SiO ₂纳米颗粒的AOT）₂，Ni（AOT）₂和Fe（АОТ）₃）。
