CONSTRUCTION OF A POLYMERIC LIQUID-MEMBRANE ION-SELECTIVE ELECTRODE (ISE)AND ITS APPLICATION FOR DETERMINATION OF NITRATE IN TOMATOES
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 plasticizer and poly (vinyl chloride) (PVC) as matrix. Nitrate concentrations in t...
