文摘
- •
A Cu/Co hybrid hexacyanoferrate was electrosynthesized on GC electrodes (CME).
- •
Determination of Hg2+exploited the decrease in the oxidation current of l-cysteine.
- •
The major interfering cations were identified.
- •
Interference from Cu2+ was removed exploiting the slower kinetics towards l-cysteine.
- •
The CME was applied for the determination of Hg2+ in spiked mineral water samples.
