Here is presented a setup made of a combination of an injection valve, a hand-made chromatographic microcolumn and an electrochemical detector for the simultaneous separation of Hg2+ and Ag+ ions in water. The microcolumns were packed with exchanger resin and used for the separation of Hg2+ and Ag+ ions, whereas a screen-printed carbon electrode (SPCE) was the amperometric detector. The performances of the SPCE towards ions were firstly studied in a FIA setup. The efficiency of ion separation was then evaluated. The reproducibility, stability, and the regeneration of the obtained microcolumns were also studied and discussed. Open Research

Abstract
Here is presented a setup made of a combination of an injection valve, a hand-made chromatographic microcolumn and an electrochemical detector for the simultaneous separation of Hg2+ and Ag+ ions in water. The microcolumns were packed with exchanger resin and used for the separation of Hg2+ and Ag+ ions, whereas a screen-printed carbon electrode (SPCE) was the amperometric detector. The performances of the SPCE towards ions were firstly studied in a FIA setup. The efficiency of ion separation was then evaluated. The reproducibility, stability, and the regeneration of the obtained microcolumns were also studied and discussed. Open Research| File | Dimensione | Formato | |
