Chloride electrode based on (TOACI) as sensor with di-n-octyl phthalate (DOPH) as mediator gives excellent response with a slop equal 60,1 mV.'decade which is the near to the Nernstian slope. Concentration was ranged from 10-2 M to 10-4 M with detection limit around 10-5 M. This electrode was used for chloride determination ion in samples using different potentiometric methods.
