摘要
论证了氟电极的洗涤和空白电位值的控制及其对测定结果的影响;提出了因氟电极空白电位值引起的稳定性和重现性差,线性范围变化及测定结果偏高、偏低甚至出现负值的解决方法.
A thorough study was made on the influence of the mode of washing of the fluoride ISE and the control of the blank potential value on results of determination. It is found that the blank potential value of the F^-electrode may lead to unstable response, subjective errors, variation of range of linearity or even negative values. A method for the solution of the above mentioned questions is proposed.
