  • Potentiometric Mg2+ Sensor and Method thereof
    Publication number: 20090020423
    Abstract: A potentiometric Mg2+ sensor is disclosed, wherein the potentiometric SnO2/ITO-based Mg2+ ISE was developed in this invention. The magnesium ion-selective membrane was fabricated and dripped on the surface of SnO2. The performance, such as sensitivity, was exhibited by the magnesium ion-selective membrane having magnesium ionophore, K-TpClPB, plasticizer, PVC in the suitable ratios. Moreover, the Mg2+ ISE was measured in different Mg2+ concentration buffer solutions. According to the experimental results, the best sensitivity of the Mg2+ sensor is 31.7l mV/decade between 10-4M and 10-1M, and measurement time is 30 sec.
