Abstract

The electrochemical reduction of a series of water-insoluble aromatic nitro compounds with coulometrically generated chromium (II) has been investigated. Samples ranging from 0.2 to 0.5 μmol could be determined for several substances with a precision and accuracy of about 1%. The number of electrons involved in the reductions corresponded in most cases to the formation of hydroxylamines or amines, but in some instances to dihydrazo products.
