Title

ATOMIC ABSORPTION SPECTROMETRIC DETERMINATION OF LEAD AFTER EXTRACTION AND PRECONCENTRATION WITH 5-BR-PADAP

Pages

  1-8

Keywords

2-(5-BROMO-2-PYRIDYLAZO)-5-DIETHYLAMMINOPHENOL 

Abstract

 Lead is quantitatively retained on 2-(5-bromo-2-pyridylazo)-5-diethylamminophenol (5-Br-PADAP) -ammonium tetraphenylborate with microcrystalline naphthalene or by a column method in the pH range 4.0-6.0 from a large volume of aqueous solutions of various samples with preconcentration factor of 60. After filtration, the solid mass consisting of the lead complex and naphthalene was dissolved with 5 mL of dimethylformamide and the metal was determined by ATOMIC ABSORPTION SPECTROMETRY. The calibration curve is linear in the range of 1.9-180 mug/mL in DMF with a relative standard deviation of 1.7%. The interference of a large number of anions and cations has been studied.
