摘　　要：目的 :研究了木犀草素 Cu( )修饰碳糊电极在 p H 2 B- R缓冲溶液中的电化学中扫速与峰电流及峰电位的关系。方法 :循环伏安法。结果 :发现木犀草素 Cu( )氧化还原峰电流正比于扫速。当扫速增加时 ,氧化还原半波电位基本不变 ,峰电位差有小幅增加。结论 :木犀草素 Cu( )Objective: To investigate the correlation of the scan rate with the spike potential and peak current in the electrochemistrical properties of luteolin metal-Cu(Ⅱ) complex modified carbon paste electrode in pH 2 B-R buffer solution. Method: Cyclic voltammetry method was used. Result: The oxidoreduction peak current of luteolin metal-Cu(Ⅱ) complex was related to the scan rate, and the oxidoreduction half-wave potential did not change with increasing scan rate, with a little increase in the spike potential difference. Conclusion: The electrochemsical properties of luteolin metal-Cu(Ⅱ) were not found to be potential scan rate dependent.
