Stable layers of oxyethylated alcohols adsorbed on the surface of a hanging mercury drop electrode under tensammetric conditions
The stability of adsorbed layers on a hanging mercury drop electrode was examined for oxyethylated alcohols (18-14, 18-10, 18-6, 10-14 and 6-14 where the first number denotes the number of carbon atoms in the n-alkyl chain and the second, the number of oxyethylene sub-units), Triton X-100 and for 18-14/10-14 and 18-14/Triton X-100 mixtures. The film stability was assessed in terms of the number of repetitions of the tensammetric peak recorded at the mercury drop after 5 or 10 min of adsorptive preconcentration
