【Abstract】 A PVC film ion sensitive field effect transistor (ISFET) chemical sensor is prepared by using (C 6H 5) 4BNa as electrical active material.When the solution concentration of hexadecyl trimethyl ammonium bromide is between 1.00×10 -3 ～2.00×10 -6 mol/L,the relation of V Gout of the sensor and the concentration of it is accord with the Nernst equation,and the slope of responding is 60 mV/pC.Besides,the sensor shows better selectivity,reproducibility and stability.更多还原
