本文报道利用植物叶提取出的叶绿素研制出的PVC(聚氯乙烯)膜叶绿素传感电极,测验其特性及Nernst响应范围。检测限为5.0×10~(-7)mol/L,可直接用于植物叶中叶绿素的测定,选择性好,干扰少,方法简便快速。
In this paper, a chlorophyll sensing electrode made of chlorophyll extracted from plant leaves was used to test its characteristics and Nernst response range. The detection limit is 5.0 × 10 ~ (-7) mol / L, which can be directly applied to the determination of chlorophyll in plant leaves with good selectivity and less interference. The method is simple and rapid.
