摘　　要：设计并制作了一种新型长光程薄层光谱电化学池 ,其具有光程长、灵敏度高、重现性好等特点 ,且组装简便 ,电极容易更换 ,溶液未补偿电阻小 ,溶液用量少 ,易清洗 .电解池以石墨为工作电极 ,分别用循环伏安、交流阻抗技术、光谱恒电位技术对其性能进行测试 。A new type of long optical path thin layer spectroelectrochemical cell is designed and constructed. This design has the following advantages over conventional spectroelectrochemical cells: long optical path, high sensitivity and good repeatability; simplicity of fabrication; the convenience of transforming electrode; small uncompensated solution resistance; small volume of solution; ease for washing cell. With graphite working electrode, using ferric/ferrocyanide in aqueous as the test species, the optical and electrochemical responses were evaluated by using cyclic voltammetry, AC impedance, constant potential control in situ spectrum and single potential step chronoabsorpometry.
