文摘
- •
Methylmercury detection by ECVG-AFS without pre-separation by HPLC is proposed.
- •
Methylmercury is atomized by direct electrochemical reduction with no reductant.
- •
Remarkably better sensitivity is obtained than the traditional HPLC-UV-AFS method.
- •
Glassy carbon is the best cathode material to generate Hg vapor from methylmercury.
