DETERMINATION OF MANGANESE IN WAFER AT PARIS PER BILLION LEVELS BY ATOMIC ABSORPTION SPECTROPHOTOMETRY.

M Z HASAN

Abstract


A method is described for the determination of ppb lovels of manganese in the presence of higher amounts of iron in water. The method involves complexing of manganese with APDC and NaDDC under stabilised condition and two step extraction of Mn2+ in acidic aqueous medium. Detection limits and sensitivity for original aqueous sample are 2 and 3 ppb respectively.

Keywords


Manganese, water, atomic absorption spectrophotometry, sodium diethyl dithiocarbamate, methyl isobutyl ketone, ammonium pyrrolidine dithiocarbamate.
