Abstract | ||
Amethod for the simultaneous determination of iron (III) and copper (II) in a mixture by derivative spec trophotometry is described .The method is based on the complexes formed by both metal ions with 6-(5-chloro-2- hydroxy-3-sulfophenylazo)-5-hydroxy-1-naphthalene sulfonic acid (Mordant blue-9) in acidic medium. The range of determination is between 5- 30µg/25ml and 5-35µg/25ml for iron and copper respectivel | ||
