Fabrication of a novel iron(III)-PVC membrane sensor based on a new 1,1a super(2)-(iminobis(methan-1-yl-1-ylidene))dinaphthalen -2-ol synthetic ionophore for direct and indirect determination of free iron species in some biological and non-biological samples

In this novel, the iron(III)-PVC membrane sensor was investigated based on a new 1,1a super(2)-(iminobis(methan-1-yl-1-ylidene))dinaphthalen -2-ol (IBMYD) synthetic ionophore as a suitable carrier. The best performance was observed for the membrane composition including 33.0% PVC, 65.0% TEHP, 1.0% N...

Description
Summary:In this novel, the iron(III)-PVC membrane sensor was investigated based on a new 1,1a super(2)-(iminobis(methan-1-yl-1-ylidene))dinaphthalen -2-ol (IBMYD) synthetic ionophore as a suitable carrier. The best performance was observed for the membrane composition including 33.0% PVC, 65.0% TEHP, 1.0% NaTPB and 1.0% ionophore. The electrode displayed a linear potential response over a wide concentration range from 1.0A-10a7 to 1.0A-10a1 molLa1, with a detection limit of 5.0A-10a8 molLa1 and a good Nernstian slope of 19.9Ac0.3mVdecadea1. The sensor possessed some advantages such as short conditioning time, very fast response time (
