Determination of saccharin in pharmaceuticals by high performance thin layer chromatography / Određivanje saharina u farmaceutskim preparatima primenom visoko efikasne tankoslojne hromatografije
(Srpsko hemijsko društvo, Beograd, 2006)
A simple, accurate and selective high performance thin layer chromatographic method for the determination of saccharin in pharmaceuticals has been developed. The chromatography was performed on silica-gel 60F254 plates ...
Spectrophotometric investigation of complex formation between HMPAO and palladium(II) ions
(Srpsko hemijsko društvo, Beograd, 1996)
A system containing palladium(II) ions and dioxime HMPAO (H 2 L; L 2 = 4,8-diaza-3,6,6,9-tetramethylundecane-2, 10-dione dioximate ion) was investigated within a pH range of 2.0 to 7.5 (1 = 0.5 mol dm 3 ) using spectrophotometric ...
Anticoagulant effect of tungstophosphoric acid salt studied by IR spectroscopy
(Srpsko hemijsko društvo, Beograd, 1996)
The influence of the Li and Na salts of 12-tungstophosphoric acid H3P W12O40(WPA) was tested for in vitro effects on blood coagulation. It was found that only Li3WPA shows anticoagulant effects, but compared with WPA ...
