本文研究了以四苯硼钠为电活性物的涂碳罂粟碱敏感膜电极。该电极的线性范围为2.82×10~(-(?))～1.00×10~(-6)mol/L.检测下限为3.30×10~(-7)mol/L。斜率为59·0mV。用格氏作图法测定了盐酸罂粟碱注射剂,其含量为标示量的100.4%,cv为124%.回收率为99.0%～101。0%。cv<2.5%。
In this paper, tetraphenyl boron sodium as the electroactive substance coated with carbon papaverine-sensitive membrane electrode. The linear range of this electrode was 2.82 × 10 ~ (-1) ~ 1.00 × 10 ~ (-6) mol / L with the detection limit of 3.30 × 10 ~ (-7) mol / L. The slope is 59.0mV. The papaverine hydrochloride injection was determined by the method of Grignard mapping, the content of which was 100.4% of labeled amount, cv was 124% and the recovery was 99.0% ~ 101.0%. cv <2.5%.
