Abstract

It is shown that one of the factors affecting the detection limit of the copper(II) sulphide precipitate-based electrode is dissolution of the membrane material. The dissolution of copper ions from the membrane can be decreased by suitable treatment of the electrode precipitate with sodium sulphide. The adsorption of the primary ion on the electrode surface in the concentration range below 10-4 mol l-1 copper ion is also shown to be a significant factor influencing the detection limit of this electrode.
