The highly selective and sensitive PVC based membrane sensor was fabricated by using 1,3,5-tris[(2,3dihydroxybenzylamino) aminomethyl]cyclohexane (L) as a neurtal membrane carrier for the potentiometric determination of citrazine. The membrane with the composition of 30% PVC, 66% o-NPOE, 3% ionophore and 1% NaTPB was found to be best in terms of response characteristics of sensor assembly. The proposed membrane sensor has very low detection limit of 2.0 x 10−8M, within the concentration range of 5.0 x 10−8– 1.0 x 10−2M, and has fast response time of about 10s. The proposed sensor was used for the selective determination of citrazine in different synthetic as well as real sample.
