摘要: The stability constants of the iron(II)-nyoximine chelates: Fe(Nyox. H)* and H)2 in aqueous NaClO4 -Britton-Robinson buffer solutions have been determined polarographi- cally. In Fe(II)-nyoxime system appears a catalytic wave in presence hydroxylamine, with half potential -0.90 V (vs. SCE), suitable for quantitative polarographic determination also hydrazine.
