摘要：

The bacterial electrode for amperometric determination of iron ions is based on a Clark-type oxygen electrode, on the measuring part of which a paste containing a mixture of jarosite precipitate and iron-oxidizing bacteria is mounted with the aid of a cellophane membrane. In acidic media a biochemical oxidation of Fe2+ connected with oxygen consumption takes place in the biocatalytic layer. Fe3+ is determined after its reduction to Fe2+. The determination limit is 60 μmol/L, the stability of the electrode is two months at room temperature. © 1990 ACADEMIA, Publishing House of the Czechoslovak Academy of Sciences.
