Acta Chrom. 11, 171-182 (2001). The chromatographic behaviour of some cations (Ni2+, Co2+, Cd2+, Cu2+, UO22+, VO2+, Fe2+/3+, Al3+, Th4+, Mo6+, W6+, Pb2+, Hg+/2+, Bi3+, Ag+, and Tl+) and anions (CrO42-, Cr2O72-, IO3-, IO4-, BrO3- SCN-, Fe(CN)63-, NO2-) was examined on layers prepared from 1:9 mixtures of a synthetic inorganic ion-exchanger (stannic arsenate or tin(IV) molybdosilicate) with silica gel, alumina, or cellulose with 1 % methanolic tri-n-butyl phosphate – 1 M aqueous formic acid 1:4 as mobile phase. Several binary cation separations of analytical interest were achieved. The metal ions were detected by use of conventional spot-test reagents. Separation of IO3- from NO2- and BrO3- under the same conditions, detection with 0.2 - 0.5 % diphenylamine in 2 M H2SO4. For quantitative determination the region corresponding to IO3- was isolated from the plate and extracted with 1.0 M hydrochloric acid. 1 % potassium iodide and conc. hydrochloric acid were added to the extract and the mixture obtained was titrated against Na2S2O3.

Anal. Chem. 80, 6821-6823 (2008). HPTLC of Cr3+ and Cr 6+ on silica gel in a saturated chamber with distilled deionized water and Triton-X-100 in concentrations between 0.001 and 0.1%, which is around the critical micelle concentration. Separation was achieved in seconds over 1 cm. Laser ablation was used to volatilize the chromium species directly from the chromatographic material prior to ICP-MS detection. The reliability of calibration was satisfying with precisions between 3 - 30 % and detection limits in the low ng-range. Silicium, which is present in the silica gel plate, was discussed as suitable internal standard.

HPTLC of potassium platinochloride, trans-platin, cis-platin and aquo derivatives of cis-platin on silica with acetone - water 95:5 or acetone - toluene - water 76:20:4. Detection by dipping in p-nitrosodimethylaniline. Quantification by densitometry at 515 nm. Detection limit 14 ng/spot.

Detection with ammoniumsulfide solution, K4Fe(CN)6 solution, 1 % alcoholic diphenyl carbazide, aqueous aluminon solution, 1 % ammoniacal dimethyl glyoxime and 1 % alcoholic alizarine red S solutions.
