Amitriptyline-molybdovanadate/-molybdotungstate based ion-selective membrane electrodes for determination of amitriptyline in pharmaceutical formulations and water samples

Amitriptyline-molybdovanadate and amitriptyline-molybdotungstate membranes are crystalline. Both the electrodes (A and B) showed linear response over the concentration range of 1.0 × 10− 4-1.0 × 10− 2 mol L− 1.74
