摘要：
This report describes an attempt to develop potentiometric Mg2+ sensors based on a liquid polymeric membrane. Membrane incorporating 4,5-Bis(benzoylthio)-1,3- dithiole-2-thione (Bz2dmit) as ionophore, with composition Bz2 dmit:NaTPB:NB:PVC in the ratio 2.5:2.5:65:30 (w/w), exhibits the best result for potentiometric sensing of Mg2+ ions. The proposed electrode, based on Bz2 dmitwith nitrobenzene (NB) as a solvent mediator in a polyvinyl chloride (PVC) membrane matrix, exhibited a near-Nernstian response to Mg2+ in the concentration range of 1.010-5 to 1.010-1M, with a slope of 29.2mV per decade of activity of Mg2+. The lower limit of detection was 1.010-5M. This sensor showed high selectivity with respect to alkaline, alkaline earth, transition, and heavy metal ions, except for Sr2+, and could be used over a pH range of 3.5-9.0. It can be used for at least 2 mo without considerable divergence in potentials and has a relatively fast response of10s. It was applied successfully as an indicator electrode in potentiometric titration of Mg2+ ions with EDTA.
