Aim: To determine total fluoride (TF) concentration in Na2FPO3/Ca-based toothpastes, using fluoride ion selective electrode (F-ISE) by the direct technique, it is necessary to use acid (Ac+) to hydrolyze the FPO3 2- ion and to dissolve insoluble fluoride salts bound to the abrasive. For NaF/silicaba...
