研制了以中性载体冠醚A1为电活性物的涂碳罂粟碱敏感膜电极。该电极线性范围为1．00×10(-2)～1.00×10(-5)mol／L，检测飞限为1.99×10(-6)mol／L，斜率为59.53mV／decade。用标准加入法测定回收率为98～103％，RSD=3．4％（n=10）
A carbon-coated papaverine-sensitive membrane electrode with a neutral carrier crown ether A1 was developed. The linear range of this electrode is 1.00 × 10 -2 to 1.00 × 10 -5 mol / L, and the limit of detection is 1.99 × 10 -6 mol / L with a slope of 59.53 mV / decade. The recovery rate was 98-103% with standard addition method, RSD = 3.4% (n = 10)
