Quantitative Inorganic Paper Chromatography : Sub-micro Separation and Determination of Aluminium, Iron and Titanium


PAPER chromatography of cations and anions in aqueous solution has so far been very little investigated1. Quantitative determinations have been achieved by R. P. Linstead and co-workers, who have already obtained very important results. Our present work began in 1946, and it appeared that organic solvents behave in inorganic paper chromatography as they do in organic paper chromatography. The adsorbed salt spot gives rise to a chromatogram depending from the cation and ion of the salt, the pH of its solution, the nature and the pH of the developing organic solvent. Changes in the composition of this solvent are likely to alter the chromatogram just as in organic chromatography2. Our experiments have dealt only with iron, titanium and aluminium chlorides, cobalt and nickel chlorides and nitrates, using downward development.
