Popis:	Ion transfer at an interface of organic nitrobenzene and aqueous phases was polarographically studied in the presence of humic acid using an ascending aqueous electrode. The transfer of hydrophobic tetraheptylammonium cation as a supporting electrolyte ion in nitrobenzene to the aqueous phase was greatly facilitated by the incorporation into the micelle-like humic acid aggregates formed around CMC of humic acid.
