Rare earth orthovanadate (REM-VO4; REM = Pr, Gd, and Sm)-based sensors for selective and simultaneous detection of furazolidone and metronidazole

A detailed differential pulse voltammetry (DPV) study on the electrochemical determination of furazolidone (FD) and metronidazole (MD), employing rare-earth orthovanadates (REM-VO 4 ; REM = Pr, Gd, and Sm) as electrode modifiers.
