The determination of microgram quantities of fluoride
TLDR
In this paper, a method for the spectrophotometric determination of fluoride is described, which can detect down to 0.05 p.p.m. of fluoride on a 10 gram sample with precision of rather better than ± 10% with larger amounts of fluoride.About:

The polarographic determination of aluminium
M. Perkins,G.F. Reynolds +1 more
TL;DR: In this paper, a survay is made of the methods available for the determination of microgram quantities of aluminium, together with techniques for its separation from interfering ion species, and a method involving the modification, by this element, of the polarographic characteristics of a diortho-hydroxy azo dye.

Spectrophotometric Determination of Fluoride in Groundwater Using Resorcin Blue Complexes
Zaher Barghouthi,Sameer Amereih +1 more
TL;DR: In this paper, a simple and sensitive spectrophotometric determination of fluoride in drinking groundwater has been developed using aluminium-resorcin blue complex, based on the reaction of fluoride with the coloured complex to produce colourless aluminium fluoride complex and releasing of the free ligand.
