Application
The reaction is based on the bleaching action of fluoride ions on an aluminum color complex. The fluoride test is especially suited for rapid control of fluoride concentrations. Its purpose is to define concentration ranges and to detect values which fall short of or exceed given limits. Chlorates and bromates cause white discolorations of the test paper.
