... Nitrate-containing ionic liquids as active membrane components of nitrate-selective electrodes . Abstract Two dialkylimidazolium-based ionic liquids were investigated as active components in the PVC membranes of nitrate ion-selective electrodes (ISE). ... The membranes involved contain 5% of active component and display close to theoretical response for nitrate ion. ... Moscow University Chemistry Bulletin . 2007, Vol. ... 4, P. 245 . ...
