Proposal of Mercury Isolation Procedure Using Cold Vapor Method in Combination with Voltammetric Determination Using Rotating Gold Electrode

Original language description

The optimal process of pre-treatment and activation of gold rotating disc electrode (AuRDE) before voltammetric determination of mercury is proposed. This treatment encompasses polishing of the electrode surface, electrochemical cycling, and activation.This procedure both increases determination sensitivity as well as improves determination reproducibility. The detection limit on the working electrode achieved using this approach amounted to 8.26?10-10 mol L-1for direct mercury determination in water solution (applying 200 s running accumulation). The procedure of the quantitative mercury isolation from complicated sample matrix was developed as well. It provides better selectivity and significant increase of sensitivity of mercury determination. In case of mercury isolation from one liter of water the detection limit is 6.23?10-11 mol L-1 (analyzing a greater sample volume the determined concentration could be lower).

Voltametrické stanovení rtuti pomocí zlaté rotační diskové elektrody v kombinaci s metodou studených par

Czech description

Voltametrické stanovení rtuti na zlaté rotační diskové elektrodě vyžaduje optimální ošetření elektrody. To spočívá v mechanickém očištění a elektrochemické cyklizaci v rozsahu vhodných potenciálů. Aktivovaná elektrody umožňuje stanovovat rtuť ve vodě v koncentracích 8.26?10-10 mol L. Z komplikované matrice je nutno rtuť eliminovat pomocí metody studených par.
