摘要
The characteristics, performance and application of membrane sensors based on ion-pair Brilliant Green mefenamate are described. The sensor＇s response to the mefenamate ion has the sensitivity of （86.0 ± 2.0） mV/pC over the range of 9 × 10 s-I × 10 2 mol/L and the detection limit of 4.5 ×10 s mol/L at pH 8.5-12. The sensor is easily assembled at a relatively low cost and has fast response time （5-10 s）. The proposed sensor displayed good selectivity for mefenamate ion in the presence of different substances. It was used to determine mefenamic acid in pharmaceuticals.
