摘　　要：本文将含有四苯硼钠的聚氯乙烯（PVC）敏感膜涂渍在压电石英晶体（PQC）表面，制成尼古丁传感器，该传感器在pH5．0～7．5的范围内，对1．0×10^-6～1．0×10^-2mol／L的尼古丁水溶液有很好的线性响应，检出限为8．0×10^-7mol／L。本法较紫外分光光度法有更宽的线性范围和更低的检出限。The nicotine sensor was prepared by coating the tetraphenylboron sodium-PVC sensitive film on piezoelecric quartz crystal. When the pH value was in the range of 5.0 and 7.5,the linear range was from 1. 0×10^-5to 1.0× 10^-2mol/L,with detection limit of 8. 0× 10^-2mol/L. Compared with ultraviolet spectrophotometric method,this method had wider linear range and lower detection limit.
