Eco-Friendly OSN Membranes Based on Alginate Salts with Variable Nanofiltration Properties.

ABSTRACT: In this work, membranes for organic solvents nanofiltration (OSN) based on a natural polymer, sodium alginate, were fabricated. They are chemically stable in organic solvents, including aprotic polar solvents. The unique advantage of these membranes is the absence of toxic reagents and solvents during their production. This ensures the safety and environmental friendliness of the production process. It has been shown that an operation as simple as changing the cation in alginate (Cu²⁺, Fe³⁺, Cr³⁺, Al³⁺, Zn²⁺, Ca²⁺) makes it possible to control the transport and separating properties of membranes, depending on the organic solvent being separated. Therefore, to isolate RemazolBrilliant Blue with MM = 626 g·mol^-1 fro
