抜粋

Some different types of miniaturized polymer membrane electrodes (PMEs) for chloride ion were constructed by the use of epoxy matrix membrane. The PME of the best characteristics consists of a copper wire and three coating layers of silver paste of epoxy matrix type, silver chloride and epoxy matrix incorporating about 45 wt % of an ion exchanger solution. The most suitable ion exchanger solution was 1-decanol containing 0.4 wt % of trioctylmethylammonium chloride. The thickness of coating layers were (0.2~0.3) mm at each layer and the electrode was about 1 mm outer diameter. The responses of the PME were Nernstian for (5X10-5~4X 10-2) M chloride. The noise of the PME on electrode potential was ± 0.5 mV at the lower linear response range. The selectivity coefficients (K Yr) of the PME for perchlorate and iodide were 1.3 and 1.1, respectively.
