Abstract
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.
