| 摘 要： | 在pH：2．0的B—R（Britton—Robinson）的缓冲溶液中，对制备的多壁碳纳米管，双十六烷基磷酸（MwcNT—D船）膜修饰电极进行了循环伏安法（CV）表征；分别研究了涕必灵（1BZ）在裸玻碳电极（GcE）和MWCNT—DHP膜修饰电极上的电化学行为，采用微分脉冲伏安法（DTV），以MWCNT—DHP膜修饰电极为工作电极，建立了一个简单、快速、灵敏的涕必灵电化学分析检测体系；并结合固相萃取技术，测定了环境水中涕必灵含量，检测限达到2．0×10-8mol·L-1，平均回收率为97．28％-99．40％，RSD为1．3％～2．8％（n=6）。

| Abstract: | In the B- R （Britton- Robinson） buffer solution of pH 2.0, the Cyclic Voltammetry （CV） imped~ce technique was used to study （MWCNT/DHP） modified electrode. 1he electro- chemical behavior of thiabendazole （TBZ） was investigated at GCE and MWCNTI DHP modified electrodes respectively. And it showed that TBZ had weak electrical activity and high over- potential. With DPV technique, a kind of ei~trocbemical analysis method which is simple, rapid and sensitive was developed for detertnination of TBZ. The detection limit was 2.0x 10-Smol/L. Combined with the solid phase extraction （SPE） technique, this method was applied to detect TBZ in the environ- mental water sample. And its recovery was in the range of 97.28 % ~ 99.40%, RSD 1.3 ~ 2.8 % （ n = 6）. |
