摘要：

Complexes of Na+ and K+ ions with dibenzo-18-crown-6 (6, 7, 10, 17, 18, 20, 21-octahydro-dibenzo[b, k][1, 4, 7, 10, 13, 16]hexaoxacyclooctadecin) were studied by polarography in several non-proton-donating media. Their stability constants are strongly influenced by the solvents, and vary inversely with the Gutmann donicity scale and with the Persson HDS parameter which is a measure of the hardness for these solvents. © 1990 ASEG.
