| Abstract: | A novel PTA-MMT andPF6 modified glassy carbon electrode(PTA-MMT-PF6/GCE) was prepared and successfully used for the determination of paraquat(PQ).The modified film was characterized by infared(IR) spectrometry.The charge transfer resistance of PQ on PTA-MMT-PF6/GCE was the lowest by comparing the nyquist plots of the electrode before and after modification.The cyclic voltammetric behavior of PQ on modified electrode was studied.The results showed that,in pH 8.0 phosphate buffer solution(PBS),two pairs of re... |
