FIELD: bismuth determination. SUBSTANCE: method consists in conversion of bismuth into complex compound with salicyl fluorine and cetyl peridinium with pH 1.9-2.5 in the presence of 5-10% of acetone. Quantitative registration is effected by photometric evaluation at 510 nm. Conditions of complex compound formation: (1.0-1.6) 10-4 M of salicyl fluorine and (0.8-1.6) 10-5 M cetyl peridinium. EFFECT: higher efficiency. 2 tbl
