Chromatographic separation of rare earth elements (REE) as anionic complexes with chelating aminopolycarboxylate ligand methylglycine N,N-diacetate (MGDA) was studied experimentally. A synthetic mixture La, Nd, and Eu were used to model a REE obtained from processed secondary sources such phosphogypsum (PG). In the extraction PG, REEs can be recovered MGDA obtain REE–MGDA mixture. Three strong ...

The purpose of this study was to use cation exchange resins mask Pregabalin's unpleasant taste. Dowex-50, a crosslinked polystyrene backbone, employed. DRCs were synthesised in batches with drug-to-resin ratios 1:1, 1:2, and 1:3. optimal ratio as well the time required for maximum complexation discovered. In work, an attempt made develop taste-masked Pregabalin solution using simple, rapid, cos...
