摘要：

In a factorial design study, involving the determination of F- by ion-selective electrodes, a significant interference was demonstrated for Fe, with an even more pronounced interference for Al. The fluoride leaching procedure from polluted soil showed more reliable results using 0.5 M citric acid. Determinations of extractable fluoride in polluted soils permitted the delineation of the impacted area by emissions of fertiliser factories.
