Kinetochromic spectrophotometry-III Determination of fluoride by catalysis of the zirconimn-Methylthymol blue reaction.
TLDR
There is considerably less cationic interference than in the alizarin complexan-cerium(III) or lanthanum procedure, but more serious anionic interference is encountered when phosphate, arsenate and, to a lesser extent, sulphate ions are present in the sample solution.About:

Indirect kinetic microdetermination of oxalate, citrate, and fluoride ions
TL;DR: In this paper, an indirect catalytic method for the separate micro determination of oxalate, citrate, and fluoride ions is described, which is based on the inhibition action on the catalytic oxidation reaction of 2,4-diaminophenol-hydrogen peroxide by iron.

Kinetochromic spectrophotometry—I: Determination of fluoride by catalysis of the zirconium-xylenol orange reaction
TL;DR: The reaction between slightly aged solutions of zirconyl chloride and Xylenol Orange is catalysed by the presence of substoi-chiometric amounts of fluoride, phosphate, arsenate, sulphate, citrate or oxalate and provides a method for determining fluoride in amounts from 0.5 to 5 mug in a final volume of 100 ml.

Kinetochromic spectrophotometry-II Determination of sulphate by catalysis of the zirconium-methylthymol blue reaction.
TL;DR: A direct spectrophotometric method is proposed for the determination of sulphate, based on its ability to catalyse the slow reaction between Methylthymol Blue and zirconium in slightly aged solution, with stricter control of timing.
