| Popis: | The possibility of transporting several transition metal picrates (Cu2+, Ni2+, Co2+, and Fe3+) through an active transport membrane with a pH gradient was investigated. Two new macrocyclic ligands used as carriers, 5, 11, 17, 23, 29, 35-hexa-t- butyl-37, 38, 39, 40, 41, 42-hexakis -[n-(1 -epoxyethyl)methoxy]calix[6]arene (I6-EPO) and 5, 11, 17, 23, 29, 35-hexa-t-butyl-37, 38, 39, 40, 41, 42-hexakis-[n-(2-hydroxyaminoethyl)methoxy]calix[6]arene I6-HPA), were synthesized from p-tert-butylcalix[6]arene. It was found that the membrane system studied allows separation of some transition metal cations. |
