摘　　要：采用循环伏安法和交流阻抗法,研究了铂电极表面上氯化钠对肾上腺素及其谷氨酸复合物的影响。实验结果表明氯化钠能在一定程度上抑制肾上腺素及其谷氨酸复合物的氧化,使其氧化峰电位正移,还原峰电位负移,峰电流减小,电化学反应电阻增大,氧化反应能力降低。The influence of sodium chloride on electron transfer properties of adrenaline and the compound of adrenaline and glutamic acid was investigated by the cyclic voltammetry and the alternating- current impedance in hydrochloric acid solution and sodium chloride with different concentration at a platinum electrode. The experimen- tal results indicated that the sodium chloride can suppress the oxidation of the adrenalin and the glutanic acid compound to a certain extent, cause its oxidation peak potential to shift positively, the reduction peak potential to shift negatively, the peak currents to decrease, the electrode reaction resistance to increase and oxidizing reaction ability to reduce.
