Construction of a polymeric liquid-membrane ion-selective electrode (ISE) and its application for determination of nitrate in tomatoes
(2004)
A potentiometric all-solid-state type ion-selective electrode (ISE) for NO3 - was constructed and characterized. It is based on a mixture of tetra-decyl-ammonium nitrate (TDAN) as ionophore, di-butyl phthalate (DBP) as ...
