摘要：

A fiber-optic chemical sensor for potassium ion is constructed using a plasticized poly(vinyl chloride) (PVC) membrane containing valinomycin. A hydrophobic fluorescent dye of oxazine 750 is covalently bound to PVC, and a fluorescence intensity from the PVC membrane is measured using a visible semiconductor laser as an exciting source. The sensor response is reversible to the potassium ion concentrations in the 10(-3) similar to 10(-1) M range, and a selectivity coefficient for sodium ion is 2 x 10(-3). A calcium ion sensor is also constructed using ETH1001 as an ionophore.. The sensor reversibly responds to calcium ion in the 10(-3) similar to 10(-1). M range, and the selectivity coefficient for sodium ion is 5 x 10(-4).
