The mobility of the spin label depends on the method of obtaining the CMC/PVAm gel on the surface of the glass fibre.
There is a correlation between the mobility of the spin label in the CMC/PVAm and crude oil spreading. The fluorescent mark in the CMC/PVAm gel shows defects when it is distributed on the surface of the glass fibre. Received: 27.11.23. Revised: 05.12.23. Accepted: 05.12.23. Available online: 15.12.23. A new method for assessing the quality of fibre coating based on a combination of fluorescence microscopy and electron paramagnetic resonance is presented in this work. An influence of the carboxymethylcellulose/polyvinylamine gel preparation method on the mobility of the spin label was established. The mobility of the spin label changes from 3.5 ns in the case of a polyvinylamine solution to 12.8 ns in the case of a cross-linked gel on the surface of the glass fibre. A qualitative relationship was found between the mobility of the spin label in the gel applied to the glass fibre and the rate of spreading of crude oil over its surface. This method can be used to make membranes for the separation of water-in-oil emulsions. This work was supported by the Russian Science Foundation (grant no. 23-23-00125), https://www.rscf.ru/en. |
