Abstract
The method includes transfer of iron to complex compound with organic reagent, concentration of complex obtained on sorbent and photometering. Transfer to complex compound and concentration are carried out simultaneously on sorbent, as such one uses macro-porous cationite previously modified with organic reagent to its content 0.5-0.625 g/g, as such one uses 4-2-pyridilazo-resorcine, complex compound obtained is eluted from sorbent with alkali solution at pH 11.8 – 12.3, and eluate is photometered.
