Abstract
Abstract PAN(1-(2-pyridylazo)-2-naphthol) is proposed for the solvent extraction and spectrophotometric determination of manganese, iron, cadmium, mercury, gallium, and yttrium. The reagent, which is highly specific for iron, has been applied to the determination of iron in clay and anorthosite. The separation of yttrium from lanthanum and the separation of manganese from nickel were successful.
