✦ Synopsis

An attempt to separate quite a Ia number of ions by ascending paper chromatography with a solvent mixture co acetone and hydrochloric acid, ulted in an excellent separation of at seven common ions from a mixturel. ~EHEIX~ in his series of ~ubl~~a~io~s rjh the effectiveness of the solverrt butyl ahol for the separation of the pf resent in a ternary or a quaternary mixture, ~~ethy~ ethyl or rn~th~l ~-~~ropy~ one admixed with ~~~~r~cl~loric acid was utilized by BURSTALL et ad.8 in their aration of Rh, Pd. Pt and Au. KEMBER AND WELLS~ rewmmcnded the use of solvents such 8s (i) hcxone, and hydrochloric acid, (ii) rr-butanol saturated with 3N h rt>chloric acid solvent (ii) ~o~tai~~~~ hydrogen p~~~~~de for the of I'd, Pt, Rh and Ir.
