An application of inhibited redox reactions for quantitative analysis of fluoride ions in selected pharmaceutical preparations.

Pharmaceutical preparations containing sodium fluoride as an active substance have been examined. To do it, a procedure developed previously that uses the inhibition of redox reaction in the system under investigation was employed. For determination purposes, visible range spectrophotometry and redoxometric titration enabling indirect quantitative determination of fluoride ions in preparations under examination have been applied. The satisfactory results confirmed by statistical parameters were obtained.
