| titleOfInvention | Carbonate selective membrane and electrode |
| abstract | A carbonate ion selective membrane comprises (a) a polymeric inert support material; (b) a plasticizer effective to solubilize the support material; (c) a quaternary ammonium ion; (d) an ionophore which is preferentially reactive with carbonate ions; and (e) a hydrophobic molecule effective to exclude ions other than carbonate ions. The hydrophobic molecule in the membrane assists in the «binding» of the organic constituents to the matrix, and it repels charged species, i.e. anions and cations, from the solution phase, thereby improving selectivity to the carbonate species which enters the membrane via selective complexation with the ionophore. The quaternary ammonium ion is preferably a C 7 to C 9 quaternary ammonium ion. In this case, the plasticizer is selected to be one effective to maximize the binding of carbonate ions with the C 7 to C 9 quaternary ammonium ions. The invention further provides a carbonate ion selective electrode comprising an internal reference element in electrochemical contact with the membrane described above. |
