Rapid Spectrophotometric Determination of Fluoride with Zirconium-Eriochrome Cyanine R Lake

Fluosilicato de zinco na prevenção de cárie dental em ratos

“…(1964). A seguir a determinação era feita pela técnica espectro-fotométrica de MEGRE-GIAN 17 (1954).…”

The Effects of Sodium Fluoride on Calcium Metabolism of Subjects with Metabolic Bone Diseases*

“…545 (10), urine creatinine by the Jaffe reaction (9), hydroxyproline by the method of Prockop and Udenfriend (11), and stool fat by conversion to fatty acid and extraction and titration of the resulting acidity (12). Fluoride was measured after perchloric acid distillation of samples of diet, stools, or urine (13) by reaction with a zirconium lake (14). Balance results and theoretical balance of phosphorous were calculated and charted according to the method of Reifenstein, Albright, and Wells (15), with slight modification of the scales used for charting.…”
