A membrane for use in the determination of calcium ion concentration in an aqueous solution, the membrane being of the type comprising a calcium ion selective component and a carrier material. The membrane is characterized in that the calcium ion selective component is a compound having a formula (1)
wherein
X and Y are independently selected from a group consisting of aryl, alkyl(aryl), alkenyl(aryl), alkynyl(aryl), alkyl, cycloalkyl, alkenyl, cycloalkenyl, and alkynyl radicals wherein said alkyl moiety of said alkyl(aryl) radical consists of 1-12 carbon atoms; each alkenyl and alkynyl moiety of said alkenyl(aryl) and alkynyl(aryl) radicals, respectively, consists of 2-12 carbon atoms; each aryl moiety consists of 6,10,12, or 14 carbon atoms; and each alkyl, cycloalkyl, alkenyl, cycloalkenyl, and alkynyl radical consists of 6 to 14 carbon atoms; and
Z is selected from a group consisting of alkyl radicals containing 1-12 carbon atoms; alkenyl and alkynyl radicals containing 4-12 carbon atoms; and cycloalkyl and cycloalkenyl radicals containing 6 to 12 carbon atoms.
The membrane can be employed in an electrode system.
