摘要
A novel method for determination of sulfide ion in water was described by screen-printed electrochemical sensor.The electrochemical behavior of N,N-dimethylphenylenediamine and catalytic oxidation of sulfide ion were studied.There was an excellent linear response range from 8.0×10-7 to 6.5×10-4mol/L（R=0.997）for the detection of sulfide ion,with a detection limit of 3.0×10-7mol/L.The method is simple,rapid,cheap and accurate.
A novel method for determination of sulfide ion in water was described by screen - printed electrochemical sensor. The electrochemical behavior of N, N - dimethylphenylenediamine and catalytic oxidation of sulfide ion were studied. There was an excellent linear response range from 8. 0 × 10^-7 to 6. 5 × 10^-4mol/L（ R = 0. 997） for the detection of sulfide ion, with a detection limit of 3.0 × 10^-7mol/L. The method is simple, rapid, cheap and accurate.
