【摘要】 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^-7mol/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。更多还原

【Abstract】 The construction and performance characteristics of a PVC membrane chlorophyll selective electrode are reported. The electrode showed Nernstian respone within chlorophyll conce-ntration of 2. 6×10^-6～2. 6×10^-4mol/L with detection limit of 5. 0×10^-7mol/L and gave fast response as well as good reproducibility. It has been applied to the determination of chlorophyll in various plant leaves with satisfactory results.更多还原
