| 摘 要： | 本文研究尼可刹米的单扫描示波极谱行为,在pH2.6的B.R.缓冲液中,于-1.28V(vs.CE)呈现一还原电流峰,与其含量有线性关系,线性范围是4.5×10~(-8)～4.0×10~(-8)mol/L,4.0×10~(-8)～8.0×10~(-8)mol/L。还用多种手段详细研究了极谱波的性质,确定其波是不可逆吸附还原波。

| Abstract: | In 0.01mol/L B.R. buffer (pH=2.6) by using oscillopolarograph, Nikethamidum is reduced and pre-sent a polarographic wave at -1.28V(vs. SCE). The determination limit is 4.5×10~(-8)mol/L, and deter-mination range is 4.5×10~(-8)～4.0×10~(-6)mol/L, 4.0×10~(-6)～8.0×10~(-6)mol/L. The properties of the polarographic wave has been studied by various techniques. It asw shown that polarographic wave was irreversibleand present adsorption. |
