The differential capacitance of mercury in pure and coumarinated I.0 N aqueous solutions of Na,SO,, HZS04, KNO+ KCl, HCl and KBr respectively was traced over appropriate potential range at 1 K Hz and 25Β°C. In NalSO., and H,SO,, assumed not to exhibit specific anion adsorption, the results were most
Ahtract-Coadsorption of perchlorate ions and 3-methyl-isoquinoline molecules at the mercury-aqueous solution interface results in the formation of a condensed film. The process of ClO; incorporation (or removal) is very slow. Characteristic relaxation times (about 10-l s) are several orders of magni
