摘要：
A new potassium ion selective electrode is proposed, in which the KTiOPO4 single crystal membrane is used as the electroactive material. The slope of response is determined to be 58mV/ -1ga(K) by means of computer fitting. The selective coefficients in relation to Na+ is 4.0 x 10(-4). The advantages of this electrode are that its slope can be hardly influenced by the variation of the pH value; its stability, repeatability and its long lifetime as well.
