【摘要】 报道了氯化血红素在肉豆蔻酸-双层类脂膜修饰玻碳电极上的电化学行为。在0.1~-0.7 V(vs.Ag/AgCl)电位范围内,扫描速率为40 mV/s时,氯化血红素在-0.4 V处产生很灵敏的还原峰电流。于pH7.50.01 mol/L KH2PO4-Na2HPO4底液中,该氧化峰电流与氯化血红素浓度在7.32×10-9~1.57×10-6mol/L范围内呈良好线性关系。该电极可作为检测氯化血红素的新型的高灵敏度电化学生物传感器。更多还原

【Abstract】 This work reports the electrochemical behavior of hemin at a lipid-myristic acid modified glassy carbon electrode(GC).In the potential range of +0.1-(-0.7) V(vs.Ag/AgCl),an irreversible cathodic peak was observed at-0.4 V at the scan rate of 40 mV/s.In the medium of 0.01 mol/L KH2PO4-Na2HPO4(pH 7.5),the cathodic peak current shows linear relationship with the concentration of hemin in the range of 7.32×10-9-1.57×10-6 mol/L.It can be used for determining hemin with high sensitivity.更多还原
