Abstract

Thick-film graphite electrodes produced by screen-printing have been investigated as inexpensive disposable potentiometric sensors for determination of heavy metal ions. The modification of graphite paste with copper sulfides caused an improvement of the analytical characteristics of the sensors. The electrodes based on Cu₂S-doped graphite film are useful for reproducible, fast, and selective determination of copper ions with Nernstian sensitivity in a wide range of concentration.
