摘要:
采用水合肼还原法制备了多壁碳纳米管(MWCNT)-石墨烯(GR)纳米复合物(MWCNT-GR),并采用滴涂法制备了此纳米复合物修饰的玻碳电极(MWCNT-GR/ GCE),研究了该修饰电极上异烟肼(Isonia-zid,INZ)的电化学行为.结果表明:在 pH 值为4.0的 HAc-NaAc 缓冲溶液中,异烟肼在0.35 V 处产生一灵敏的不可逆氧化峰.线性扫描伏安法测定异烟肼的线性范围为1.0×10-7~1.0×10-4 mol·L -1,检出限为5.0×10-8 mol·L -1(S/ N =3).用该法测定了异烟肼注射液中异烟肼的含量,结果令人满意.
Abstract:
The multi-walled carbon nanotube / graphene composite(MWCNT-GR)were synthesized by using hydra-zine as a reduction agent. Based on this,a MWCNT-GR composite film modified glass carbon electrode(MWCNT-GR/ GCE)was fabricated. The electrochemical behavior of isoniazid(INZ)on this modified electrode was investi-gated carefully. The results showed that an irreversible oxidation peak at 0. 35 V of ING was observed on cyclic vol-tammograms in HAc-NaAc buffer solution(pH 4. 0). The linear range for determination of INZ by LSV was 1. 0 × 10 - 7 ~ 1. 0 × 10 - 4 mol·L - 1 with the detection limit of 5. 0 × 10 - 8 mol·L - 1(S / N = 3). Finally,this method was successfully employed to determine isoniazid in injection.
