摘要：

Ion-selective electrodes (ISEs) were developed by impregnating plasticized poly(vinyl chloride) membranes with a complex of triisobutylphosphine sulfide and Hg2+. The electrodes were selective for halides and thiocyanate, iodide being the preferred anion. The overall selectivity pattern of the electrodes was I-> SCN- almost-equal-to Br- > Cl- > NO2- almost-equal-to ClO4- > NO3- almost-equal-to SO42-. The electrodes were evaluated in both batch and flow-injection modes.
