Determination of Trace Amount of Iron (II) in the Presence of Iron (III) using Extraction Formation Method

The suitability of 3-(2-Pyridyl)-S,6-(diphenyl>-l,2,4-triazine (PDT) as a reagent for determination of iron (II) in presenoe of iron (III) is evaluated. The studies were made of the tris (pDT)-iron (II) complex formed in strong acid solution and its extraction in chloroform and also in l,l,l-trichloroethane. This serves as a useful method for the determination of microgram quantities of iron !II) in 'presenoe of iron (III).
