Abstract
The posibility of macrocyclic ligands: 18-crown-6, dibenzo-18-crown-6 and dicyclo-hexyl-18-crown-6, to complex the amino acids (L-leucine, D L-tryptophane, L-isoleucine, L-phenylalanine, L-valine and glycine) in protonated form were studied. The extraction constants were determine d by a spectrophotometric visible absorption method. Diphenylamino-azo benzene-p-sulphonic acid anion was use as counterion.
