Abstract (EN): A simple method for fluoride determination in Spanish vinegars has been developed to provide direct data on dietary fluoride intake from this product. This paper describes a potentiometric method that uses a fluoride selective electrode. Three different TISAB (total ionic strength adjuster buffer) solutions have been evaluated and the method of multiple known additions was used. The precision and accuracy of the developed procedure, in terms of variation coefficient (0.74%) and average percentage of spike recovery (99.9%), are adequate. Forty-two samples of Spanish vinegars were analyzed obtaining a range of fluoride content between 0.12 and 1.95 mg dm-3 with an average concentration of 0.52 mg dm-3.
