レニウム(VII),モリブデン(VI),タングステン(VI)の薄層クロマトグラフィー

抄録

Separation of rhenium(VII), molybdenum(VI) and tungsten(VI) can be effected by thin-layer chromatography on an alumina-coated polyethylene terephthalate film (Eastman Chromagram Sheet 6062, 100 μ thick) in simple aqueous solutions of acids or salts. All the solvent systems tested which include the dilute aqueous solutions (<0.1N) of thiocyanic acid, ammonium thiocyanate, hydrochloric, acetic, oxalic, malonic, tartaric, citric acids and ammonia, are found to give the most favorable resolution of the three elements. R_f values are in the order Re (VII)>Mo(VI)>W(VI) irrespective of the developing solvents.
