Abstract
Ammonium exchange with hybrid PVC–bentonite (mineral montmorillonite clay) thin film was revealed using FTIR spectroscopy, EDX, cyclic voltammetry and electrochemical impedance spectroscopy. The effect of ammonium exchange on the charge transfer resistance of PVC–bentonite hybrid thin film was attributed to a modification of the intersheet distance and hydration of bentonite crystals.
tained impedimetric ammonium sensor shows a linear range of detection from 10− 4 M to 1 M and a detection limit around 10− 6 M.
