【摘要】 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）更多还原

【Abstract】 The neutral carrier membrane electrode of papaverine was developed for the quantitative determination of papaverine in Chafing dish. The electrode showed a linear response to papaverine within the concentration range of 1. 00 × 10(-2) ～ 1. 00 × 10(-5) mol/L, the limit of detection was 1. 99 × 10(-6) mol/L,and the slope was 59. 53mV/decade. The papaverine in sample of Chafing dish was determined by standard addition method, The recovery was 98 ～ 103%, RSD = 3. 4 N (n = 10).更多还原
