S. Iskric et al., BEHAVIOR OF HUMIC ACIDS ON FE(III)-IMPREGNATED SILICA-GEL COMPARED WITH MODEL SUBSTANCES, Journal of liquid chromatography, 17(7), 1994, pp. 1653-1657
Behaviour of humic acids under the conditions of thin layer chromatogr
aphy on Fe(III)-impregnated silica gel with tap water as developer was
investigated. Compounds having similar functional groups as the humic
material were compared and conclusions extended to natural conditions
were drawn.
