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)
