Spectrophotometric determination of fluosilicic acid in hydrofluoric acid
Abstract: A procedure is reported for the spectrophotometric determination of fluosilicic acid in commercial hydrofluoric acid. The determination of silicon as (?)a-silicomolybdic acid is carried out directly without previous separation of hydrofluoric acid. Title of Study: Studies in the spectrophotometric determination of silicon in materials decomposed by hydrofluoric acid: Spectrophotometric determination of fluosilicic acid in […]
