| Abstract: | An optical ion-sensing system based on a PVC membrane containing a Li+ ionophore in combination with a H+ selective chromoionophore (ETH 5294) is presented. It exhibits an absorbance response to Li+ concentration in pH buffered solutions. The dynamic range and Li+/Na+ selectivity of this new optode system are discussed. |
