What is the AFI purity level of hydrofluosilicic acid?

The AFI (American Fluoridation Initiative) purity level of hydrofluosilicic acid is 0.23. This value indicates the concentration of active fluoride ions in the hydrofluosilicic acid solution, which is significant for ensuring that the water fluoridation process is effective and meets public health standards. Hydrofluosilicic acid is commonly used in water treatment for fluoridation purposes, and understanding its purity level helps operators accurately calculate the dosage needed to achieve the desired fluoride concentration in drinking water. Maintaining the correct purity level is essential for both regulatory compliance and public health safety.
