Differential pulse polarographic behaviour of azodicarbonamide : application for indirect determination of Co2+ in aqueous solution

الملخص EN

The differential pulse polarographic behaviour of azodicarbonamide has been investigated in Britton Robinson buffer.

The peak obtained at pH 7.5 is recommended for trace determination of this compound.

The lowest experimental detection limit is shown to be l.OxlO-6 M with a relative standard deviation of 4%.

The method was successfully applied for the indirect determination of Co2+, and as low as 8.3x10-8 M> was detected.
