Abstract

A membrane responsive to nitrate has been developed; it is composed of a polymer matrix, an anion exchanger (tridodecylmethyl-ammonium chloride), and a polarity-sensitive dye (rhodamine B octadecyl ester perchlorate). On exposure to nitrate, its fluorescence intensity increases, while the wavelength of the excitation and emission maxima remain unchanged. The effect of the polymer matrix on the ...
