摘要：

The present study has shown that the cadmium content of wine can be greatly reduced by two treatments normally associated with the removal of copper and iron from wine. The European treatment requires the addition of tetrapotassium hexacyanoferrate (II), K4[Fe(CN)6] to the wine, whereas in the United States, the FDA-approved method, involves the use of a formulation known as the Fessler's compound, which contains the Williamson salt i.e. iron (II) potassium hexacyanoferrate (II), K2Fe[Fe(CN)6]. For a test wine very lightly loaded with iron and consequently requiring the addition of only a very small quantity of iron remover, 72-82% of the cadmium can be eliminated. At higher iron concentrations where the amount of reagent added is increased, the removal of cadmium from the same wine can be as great as 95%. © 1990 Taylor & Francis Ltd.
