| Abstract: | The characteristic factors of fluorine ion-selective electrode analysis to determine the fluoride are verified.It shows that the RQL is 0.04 mg/L,the standard deviation is 0.0026, the RSD is 〈2.7 %,and the rate of recovery is between 97-103%. The precision and accuracy of this method is fine and meets the requirement of quality control. |
