| Abstract | ||
| A thallium(I) selective electrode based on phenyl disulfide as membrane carrier was prepared. The electrode exhibits a near-Nernstian response for Tl+ ions over a wide concentration range from (1.0x10-5-1.0x10-1 M) with a slope of 56.9 mV/decade and a limit of detection of 5.6x10-6 M, and was found to be selective and useable within the pH range (4.0-10.0). The electrode was successfully used as an indicator electrode in potentiometric titration of thallium ions. | ||
