| Abstract: | The construction and general performance characteristics of the piezoelectric sensors responsive to sulpha-drug are described here. The proposed sensing method is based on the use of the ion-pair complex of sulphadiazine-cetyltrioctylammonium. The complex, together with cholestyramine was embedded in PVC matrix. This sensor exhibited reasonable selectivity and a sensitive mass response to sulpha-drugs. The response range of the sensor was between 1.0x10(-7) and 1.0x10(-5) M with a detection limit of 8x10(-8) M at pH 8.63. The influencing factors were investigated in detail and optimized. |
