Abstract
FIELD: analytical methods. SUBSTANCE: method allows determining small amounts of cobalt in presence of great contents of nickel, tungsten, molybdenum, and multiple complexing agents: citric, tartaric, ascorbic, and salicylic acids, and thiourea in strong-acid medium. Determination of cobalt is performed with quinolineazo-P compound in hydrochloric acid medium (2 M solution) with no preliminary separation of basis which increases selectivity, accuracy, and quickness of analysis. EFFECT: improved procedure.
