用石墨粉50％、α-溴代萘20％和甘油30％制备了混合粘合剂碳糊伏安传感器。在0.030mol/LHCl溶液中,当有0.040％SLS存在时,利眠宁在-0.80V左右产生一灵敏的阴极溶出伏安峰、在-0.20V处富集150s,线性范围为1.O×10~(-8)～4.0×10~(-7)mol/L,检测下限为1.0×10~(-9)mol/L。循环伏安实验结果证实利眠宁在碳糊电极上的吸附为反应物吸附。
A mixed binder carbon paste voltammetric sensor was prepared using 50% graphite powder, 20% α-bromonaphthalene and 30% glycerol. In the 0.030mol / LHCl solution, when there is 0.040% SLS exist, dipyridamole at -0.80V or so produce a sensitive peak cathodic stripping peak at -0.20V enrichment 150s, the linear range of 1.O × 10 ~ (-8) ~ 4.0 × 10 ~ (-7) mol / L, the detection limit was 1.0 × 10 ~ (-9) mol / L. The results of cyclic voltammetry confirmed that the adsorption of chlordiazuron on the carbon paste electrode was the reactant adsorption.
