Abstract : A new nitrate selective electrode has been developed. This electrode uses a derivative of bis-thiourea as
ionophore. Bis-thiourea derivatives obtained from the reaction between bis (aminomethyl) benzene with
nitrophenylisothiocyanate. Nitrate selective electrode showed near Nerstian values -54.7± 3.5mV/dec with RSD value is
6.5% . Meanwhile, the linear range is 0.1 M - 10-5 M and the sensor has a detection limit is 4.1 x 10-6 M. In this study, Log
Kpota,b values are given for each interference ion is Cl- -1.36 ± 0.12, HPO4
2- -2.80 ± 0.24, Br- -0.58 ± 0.10, CrO4
2- -1.32 ±
0.21, SO4
2- -2.42 ± 0.31. Artificial samples, fish pond and soil used as real samples. Nitrate sensors give a similar results
with commercial sensor.
Keywords- Nitrate-Selective Electrode, Bis (Aminomethyl) Benzene, Nitrophenylisothiocyanate, Bis-Thiourea.
