摘要

提出了一种基于叶绿素a作为生物电活性膜载体的新型PVC膜Mg2+电化学生物传感器。该传感器在Mg2+浓度范围为1× 10−5 M ~ 1× 10−1 M范围内呈现出能氏响应，斜率为30.41 mV。并对Mg2+的响应时间和选择性进行了研究。

Eletrochemical Detection of Magnesium Ions Using PVC Membrane Trapped Chlorophyll A Molecules

Abstract This paper presents a novel PVC membrane electrochemical biosensor for Mg2+ ions based on chlorophyll a as bioelectroactive membrane carrier. The sensor displays a Nernstian response for Mg2+ concentration range from 1× 10−5 M to 1× 10−1 M with a slope of 30.41 mV. The response time and selectivity for Mg2+ in comparison to some other cations have also been studied.
