Fluoride in ceramic materials
Özet
Fluoride contents in ground soil, water, wastewater samples and some coal samples were investigated. It was observed that naturally occurring fluoride in these environments is ?200ppm for solids and ~1.3 mg/L for seawater. The range of fluoride concentrations of the raw material samples tested in this work was dependent on the analytical method used, especially when the collective data of 55 national reserves in Turky was taken into account. The eriochrome cyanine R (ECR) method, the ion selective electrode (ISE) and the SPADNS zirconium lake methods for measuring the fluoride concentrations were also analyzed. .
