Abstract
Dicationic type anion-exchange extractants, CnBP, extracted organic dianionic species to a much greater degree as compared with classical monocationic extractants (Capriquat, etc.). This high extraction ability was applied to poly(vinyl chloride) (PVC) membrane electrode (coated-wire type). The electrode was found to be highly selective to 1,5-naphthalenedisulfonate anion (NDS2−).Keywords
