摘要
采用氧瓶燃烧法.利用氟离子选择电极测定了茶叶及防龋健齿口腔中氟离子的含量,并做了回收率实验,实验证明,本法准确度高.回收率好,简便易行。
A potentiometric determination of micro fluorine in tea and chewing-gum for preventingdecayed tooth by oxygen flask combustion method and fluorine ion selective electrode is re-ported- The result shows that this method is simple, rapid and accurate, and the average re-covery is 99. O%.
