Abstract
A TLC method has been developed for the separation of microgram quantities of Fe(II) from milligram quantities of Fe(III) by using formic acid-butanol-ethyl methyl ketone as mobile phase. The separation is not effected by the presence of chloride, bromide, sulfate, sulfite, acetate and phosphate ions. Good separation was achieved when the pH of the sample solution was kept near to 1.0.
