PHOTOMETRIC PALLADIUM(II) DETERMINATION METHOD

摘要

FIELD: analytical methods. ^ SUBSTANCE: invention relates to analytical chemistry of platinum metals and may be used when determining palladium in refining production process nitrite solutions. Method comprises formation of colored complex compound of palladium(II) with nitroso-R-salt in solution in presence of sodium nitrite at pH 4-6, whereupon optical density of the complex at 520 nm is measured. ^ EFFECT: increased sensitivity and information value of analysis. ^ 1 tbl, 3 ex
