Abstract
Abstract The Orion potassium ion selective electrode (92–19) has been evaluated in terms of Nernstian response, selectivity, anion, and pH effects. The response is slightly less than Nernstian and a linear calibration curve is obtained over the concentration range 10−4 to 10−1 M potassium, The calculated selectivity ratio for potassium over sodium depends on the relative concentrations of sodium and potassium. Slight anion effects are noted with the most significant occurring with iodide, hydroxide, chromate, and oxalate. Tetraphenyl borate ion causes a large negative potential shift and this effect appears to render the electrode only moderately useful for titrations with this reagent.
