Electrochemical detection of magnesium ions using PVC membrane trapped chlorophyll A molecules
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 X 10(-5) to 1 X 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.
