Bulletin of Gulistan State University
In this study, technical sodium carboxymethylcellulose (Na-CMC) with degree of substitution (DS) = 0.62-0.90 and a degree of polymerization (DP) = 200-600 were washed in 70% ethyl alcohol and a 2% fraction of purified Na-CMC was centrifugation at a speed of 6000 rpm for 20 minutes. A 0.1 M solution of SeO2 was added to the centrifuged Na-CMC solution at 60 ⁰C and mixed mechanically. Samples of gels, films and powders containing a solution of Na-CMC containing stabilized selenium nanoparticles synthesized by chemical reduction were taken and their physicochemical properties were studied. The size and shape of selenium nanoparticles present …
