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 […]

Fluoride adsorption by clay minerals and hydrated alumina
Research Article
Extract In the course of some studies on the effects of anions on the viscosities of clay suspensions, it was observed that anions such as pyro- and metaphosphate, oxalate and fluoride were much more effective in reducing the viscosity of kaolih suspensions than were chloride and nitrate. There is relatively little information available regarding the […]
