Fluoride separation

The aim of this work is the optimization of distillation process using H SO for fluoride separation and potentiometric determination in anhydrite samples by means of chemometric tools. [Pg.271]

Ions of metals forming complexes with sulphosalicylic acid or fluoride, as well as anions which react with Fe(III), interfere in the determination of fluoride. Separation of fluoride by distillation prevents the interference of foreign ions. [Pg.193]

Possible contaminants are allyl chloride and allyltin chloride. Check the H NMR and IR [Fishwick Wallbridge J Organomet Chem 25 69 1970], and if impure, dissolve it in Et20 and shake it with a 5% aqueous solution of NaF which precipitates allyltin fluoride. Separate the Et20 layer, dry (MgS04), and distil it at 0.2mm. It decomposes slightly on repeated distillation. [O Brien et al. Inorg Synth XIII 75 1972, Fishwick et al.JChem Soc (A) 57 1971, Beilstein 4 III 1922.]... [Pg.654]
