Name: 1,4,7,10,13-PentaoxacyclopentadecaneIn 2020 ,《Sorption of Metal Ions from Aqueous Solutions by Crown Ethers》 was published in Russian Journal of Physical Chemistry B. The article was written by Gromov, V. F.; Gerasimov, G. N.; Ikim, M. I.; Spiridonova, E. Yu.; Trakhtenberg, L. I.. The article contains the following contents:
The sorption of copper and lead ions by polymeric sorbents based on crosslinked polyacrylamide containing chem. bound or immobilized 15-crown-5 and 18-crown-6 was studied, as was the effect of various parameters on the efficiency of metal sorption from aqueous solutions It is shown that the sorption capacity of these sorbents increases dramatically with an increase in the content of crown ethers in them from 3 to 6 wt %. When aging sorbents containing 6 wt % 15-crown-5 or 18-crown-6, in an aqueous solution of copper chloride or lead acetate, resp., the salt concentration in the solution decreases by 3-4 orders of magnitude. When aging sorbents based on 18-crown-6 in a solution containing equivalent amounts of lead acetate or copper sulfate, the amount of absorbed copper did not exceed 5% of the amount of extracted lead, which indicates the high selectivity of such sorbents. In addition to this study using 1,4,7,10,13-Pentaoxacyclopentadecane, there are many other studies that have used 1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5Name: 1,4,7,10,13-Pentaoxacyclopentadecane) was used in this study.
1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5) is a member of crown ether Ligands. Crown-ethers are macrocyclic polyethers capable of forming host-guest complexes, especially with inorganic and organic cations. Crown-ethers can incorporate protonated primary amine compounds by formation of ion-dipole bonds with the oxygen atoms of the chiral selector. Crown-ethers have been widely used for the separation of several pharmaceuticals both in aqueous and non-aqueous media. Name: 1,4,7,10,13-Pentaoxacyclopentadecane
