Method for routine determination of fluoride in urine by selective ion- electrode

Description

A simple, fast and sensitive method is outlined for determining fluoride in urine of workers who handle fluoride compounds. The determination is based on the measurement of fluoride by ion selective electrode. Cationic interferents like Ca++, Mg++, Fe+++ and Al+++ are complexed by EDTA and citric acid. Common anions present in urine, such as Cl-, PO---4 and SO--4 do not interfere in the method. (Author)

Abstract (Portuguese)

Apresenta-se um metodo simples, rapido e sensivel para a determinacao de fluoreto em urina de pessoal que tem contato com compostos fluorados. A analise baseia-se na medida do ion fluoreto por meio de eletrodo seletivo. Provaveis interferentes cationicos como Ca++, Mg++, Fe+++ e Al+++ sao complexados por EDTA e acido citrico. Anions comumente presentes na urina, como Cl-, PO---4 e SO---4 nao interferem no metodo. (Autor)
