| 摘 要： | Electroreduction of vitamin K3 provides the basis for research andsensitive determination of vitamin K3.The Single Sweep Oscillopolaro-graphy and Neopolarography are used to explore the interracial and redoxbehaviours.The detection limits are 5×10~(-9) M(1.75ng/ml),4×10~(-9)M(1.41ng/ml)respectively for the single sweep oscillopolarography andneopolarography.The linear responses of polarographic peaks againist theconcentration are all 1×10~(-8)-5×10~(-5)M.Both methods are used todemonstrate the electrode process and determination of vitamin K3 inpharmaccutics and plasma with a satisfactory result.
