A comparative study of the sorption properties of N-(2-carboxyethyl)chitosan (CEC), N-(2-sulfoethyl)chitosan (SEC), N-(2,3-dihydroxy)propyl chitosan (HPC) and N-2-(2-pyridyl)ethyl chitosan (PEC) with respect to perrhenate ions in an acidic medium was carried out. From the anal. of the adsorption isotherms and the perrhenate ion adsorption degrees as functions of pH, the efficiency of adsorbents decreases in the sequence PEC > SEC > HPC > CEC. The studied chitosan derivatives are characterized by a higher rate of sorption of perrhenate ions in comparison with known com. anionites. In the case of PEC, accompanying ions have the least effect on the sorption. After reading the article, we found that the author used 2-(2-Hydroxyethyl)pyridine(cas: 103-74-2SDS of cas: 103-74-2)
2-(2-Hydroxyethyl)pyridine(cas: 103-74-2) belongs to pyridine. Pyridine derivatives lend themselves to many roles in the spirited field of supramolecular chemistry – whether as the ligand backbone of metal-organic polymers or presiding over the key electronic stations of nanodevices. In biochemistry, pyridine-containing cofactors are necessary nutrients on which our lives depend. SDS of cas: 103-74-2
