Spectrophotometric Determination of Iron(III) after Separation by Adsorption of its Pyrrolidinedithiocarbamate on Nephthalene
Keywords: Chelate, Adsorption, Polarography
AbstractA method for the spectrophotometric determination of trace amounts of iron(III) after adsorption of its pyrrolidindeithiocarbamate on naphthalene is presented. Iron(III) forms a water-insoluble chelate with ammonium pyrrolidinedithiocarbamate in the pH range 2.9-6.6. This chelate is quantitatively adsorbed onto mycrocrystalline naphthalene at room temperature. The effects of variablesm, such as pH, amount of reagent and napthalene, digestion and shaking time, and diverse ions, have been examined. The method has been applied to the determination of iron(III) in standard reference and environmental samples and the results compared with 1,10-phenanthroline method.
