【摘要】 用新物理量Vop的椭圆法定性地分析电化学体系已十分有效.鉴于椭圆法能灵敏检测电极表面0.1nm厚度物质的优点,如能用于定量电化学分析,可能提高现有电化学分析方法的检测限1个数量级以上.本文研究是否可能以及如何实际应用椭圆法于电化学定量分析.结果表明此法简单,并有满意的灵敏度.更多还原

【Abstract】 The experimental results show that the ellipsometry with a new parameter VOP could be analyzed qualitatively for the electrochemical systems effectively. The spectroscopy may raise the detection limit of quantitative electrochemical analysis to 10-10-10-11 mol/L because the surface film thickness at a range of 0. 01 ~0. 1 nm can be sensitively detected by ellipsometry.更多还原
