Cumulative CAMAG Bibliography Service CCBS
Our CCBS database includes more than 11,000 abstracts of publications. Perform your own detailed search of TLC/HPTLC literature and find relevant information.
The Cumulative CAMAG Bibliography Service CCBS contains all abstracts of CBS issues beginning with CBS 51. The database is updated after the publication of every other CBS edition. Currently the Cumulative CAMAG Bibliography Service includes more than 11'000 abstracts of publications between 1983 and today. With the online version you can perform your own detailed TLC/HPTLC literature search:
- Full text search: Enter a keyword, e.g. an author's name, a substance, a technique, a reagent or a term and see all related publications
- Browse and search by CBS classification: Select one of the 38 CBS classification categories where you want to search by a keyword
- Keyword register: select an initial character and browse associated keywords
- Search by CBS edition: Select a CBS edition and find all related publications
Registered users can create a tailor made PDF of selected articles throughout CCBS search – simply use the cart icon on the right hand of each abstract to create your individual selection of abstracts. You can export your saved items to PDF by clicking the download icon.
J. Planar Chromatogr. 8, 463-466 (1995). TLC of chlorides or nitrates of copper, cadmium, zinc, nickel, cobalt and lead on silica with 1.0 M sodium formate - 1.0 M potassium iodide 1:9. Detection with 0.1% dithizone in carbon tetrachloride (Zn, Cd, Pb), with 1% dimethylglyoxime in ethanol (Ni, Co), with 1% aqueous solution of potassium ferrocyanide (Cu). Titration resp. AAS determination after elution. The titrimetric determination is considered as useful for the quantification of Cu in the concentration range 100-500 µg/µl whereas AAS was useful for determination of Cu at concentrations in the range 2-8 µg/mL.
J. Planar Chromatogr. 11, 51-55 (1998). Development of a simple theoretical model for the study of the TLC behavior of metal ions. The model is represented by an equation in which the retention factor of a metal ion, the concentration of competing ion, and the constants a and b are of importance. TLC of 33 metal ions on silica gel with mixtures of methyl isobutyl ketone and formic acid. Experimental and theoretical results were in good agreement for most of the metal ions.
J. Planar Chromatogr. 15, 107-115 (2002). TLC of some metal cations on silica gel with micellar mobile phases containing sodium dodecyl sulfate; e.g. separation of Au, Cu, and Ag on silica gel with 0.01 m SDS - 0.01 M l-tryptophan or l-histidin 1:9. Visualization as coloured spots by application of appropriate detection reagents (i. a. dithizone, aqueous potassium ferrocyanide, dimethylglyoxime, aluminon, yellow ammonium sulfide). Detection limits for Fe, Cu, Zn, Cd, and Hg were also determined. Selective and rapid procedure.
Acta Chrom. 9, 113-122 (1999). Selective separation of Hg2+ from spiked sea and industrial waste water samples. TLC of some inorganic pollutants on silica gel impregnated with potassium thiocyanate (0.01 -2.0 M) 1:1 mixtures of sodium chloride (0.01 - 1.0 M) and formic acid (0.01 - 1.0 M) as mobile phases. Detection with 5 % potassium ferrocyanide in water (for Fe3+, Cu2+, UO22+, VO2+, and Tl+), 0.05 % dithizone in carbon tetrachloride (for Zn2+, Cd2+, Pb2+, Bi3+, Hg2+, Ag+, and Tl+), 1 % dimethylglyoxime in ethanol (for Ni2+ and Co2+), 0.1 % aluminum (for Al3+) and 0.01 % thorine (for Th4+ and Zr4+). The effect of surfactants, halides and oxyanions on the separation of Hg2+ from UO22+ and Fe3+ was examined. The method was used to identify Hg2+, Pb2+, Cd2+, and Zn2+ in synthetic heavy metal sludge samples.
Chromatographia 67 (3-4), 259-267 (2008). Investigation of saturated aqueous solutions of 28 different salts used as potential mobile phases for salting-out TLC, on silica gel, of a series of four mixed bis-aminocarboxylato cobalt(III) complexes. Confirmation of three alkali metal chlorides, and four alkaline earth metal chlorides, for linear dependences previously established on different adsorbents with (NH4)2SO4 solutions by linear regression analysis of chromatographic data obtained for fifteen mixed aminocarboxylato Co(III) complexes (four series) with solutions of ammonium chloride. Comparison of separation achieved with different salts. Li+, Mg2+, and Ca2+ chlorides are most suitable.
Anal. Chem. (Fenxi Huaxue) 12, 1077-1078 (1984). (Chinese). (Separation of rare earth elements by thin-layer chromatography. ) TLC of rare earth elements, La, Ce, Pr, Nd, SM, Eu, Tb and Ho on silica with monotetradecyl phosphate (p538)- ethyl acetate - nitric acid in varying proportions. The Rf values of the elements involved increase with their atomic system number.
Viewing under UV. Densitometry by absorbance at 310 nm. Detection 0.1 to 1 ng.
Chromatographia 21, 708-710 (1986). Investigation of the TLC behaviour of 49 inorganic ions on polyethyleneimine cellulose with hydrochloric acid media. The sorption on the cellulose decreases with increasing acid concentration for most of the ions, but As(III), Ti(IV) and Te(VI) do not exhibit Rf variation with acid concentration.
