  • Title: Extractive spectrophotometric determination of trace amounts of iron(III) with benzyltriethylammonium chloride.
    Author: Bayan KC, Das HK.
    Journal: Talanta; 1988 Jan; 35(1):57-8. PubMed ID: 18964465.
    Abstract:
    The ion-association complex formed between a thiocyanato-iron(III) ion and a benzyltriethylammonium ion is extracted into 1,2-dichloroethane, and its absorbance at 476 nm is used for determination of the iron. Beer's law is obeyed up to about 4 mug/ml iron concentration in the final solution. The molar absorptivity is 2.79 x 10(4) l.mole(-1).cm(-1).
