title: Spectrophotometric determination of iron(II) after separation by adsorption of its complex with 3-(4-phenyl-2-pyridyl)-5,6-diphenyl-1,2,4-triazine and tetraphenylborate on microcrystalline naphthalene.
abstract: Trace iron(II) is determined spectrophotometrically after adsorption of its ternary complex with 3-(4-phenyl-2-pyridyl)-5,6-diphenyl-1,2,4-triazine and tetraphenylborate on microcrystalline naphthalene at pH 5.1-7.4. The absorption maximum is at 567 nm; the molar absorptivity is 2.9 x 10(4)lmole(-1)cm(-1).
