摘　　要：采用三同铜电极体系,在16 g/L NaOH、20 g/L Na2SO4溶液中,采用循环伏安法检测血浆中的葡萄糖浓度。葡萄糖浓度c在0.2-2.4 g/L范围内与峰电流ipc呈线性关系,线性方程为c=5.255-5.46ipc,线性相关系数为0.9946,方法的检测上、下限分别为2.06 g/L和0.2 g/L。相对误差为0.57%-6.84%,相对标准偏差为1.27%-4.10%。The glucose was determinated by cyclic voltammetry in 16 g/L NaOH-20 g/L Na2SO4 solution on the copper electrode.The linear concentration range of glucose was 0.2-2.4 g/L with the peak current,and the linear equation was c=5.255-5.462ipc（r=0.994 6）.The lower and upper determination limits were 0.2 g/L and 2.06 g/L,respectively.The relative error and relative standard deviation of determination result were 0.57%-6.84% and 1.27%-4.10%,respectively.
