Die Chromatographische Adsorptionsmethode

The Isolation and Absorption Spectrum Maxima of Bacterial Carotenoid Pigments

“…After separation of the pigments into groups, the individual components in each group were separated by the chromatographic adsorption technic devised by Tswett (1906) and excellently described by Cook (1936). Zechmeister and Cholnoky (1937) have also presented a thorough description of chromatographic adsorption.…”

Fixation of Phosphate During the Acid Extraction of Soils

“…Fixation of phosphate during acid extraction of soils should be reduced if citric acid is used as solvent. Morin and quinalizarin, which form complexes with aluminium, prevented a great part of the fixation caused b the position of the ion in the table of absorption affinities for alumina given by Zechmeister and Cholnoky (1938). Fluoride reduced phosphate fixation by alumina markedly.…”

Chromatography: The separation technique of the 20th century

“…In earlier discussions we have already pointed out the impact of textbooks on the growth of the various chromatographic techniques, such as the book of Zechmeister and Cholnoky on classical liquid chromatography [16], the handbook of Stahl on TLC [33] and Keulemans' compilation on gas chromatography [41]. The situation was also similar in HPLC where its rapid evolution was aided by the excellent textbook written by Jack Kirkland …”
