Abstract
This article reports the electrical responses of a phosphate ionophore, the cyclic polyamine 3-decyl-1,5,8-triazacyclodecane-2,4-dione (N3-cyclic amine) incorporated into metal supported bilayer lipid membranes (s-BLM). Teflon coated silver wire was used as a support. In a potentiometric mode, the ionophore had a response that was linearly related to the logarithm of HPO42− concentration and was also dependant on pH. Selectivity coefficients for other anions compared to HPO42− ions, determined by the separate solution method, fell within the range 1.73 × 10−4 to 6.38 × 10−2.
