Sažetak
The surfactant sensitive electrodes are based on direct potentiomery and usualy based on PVC liquid membrane. PVC liquid membrane consists of the ionophore, lipophilic ionic sites, lipophilic salts (as electroactive compounds) and plasticizer (additive with a low molar mass). Plasticizer makes the rigid PVC matrix more softer and flexible. Plasticizer offers some additional benefits to the PVC sensing membrane ; it disolves ionophore and enhances the species mobility inside the membrane. The plasticizer, as a part of PVC sensing membrane, should possess some important properties ; 1) it should be insoluble in water, 2) it should prevent the ionophore leakage to the analyte, 3) it should be inert to ion exchange. The typical weight ratio of PVC and plasticizer in the sensing membrane is 1:2.
