Determination of Silver in Aluminum by Thin Layer Chromatography
نویسندگان
چکیده
Small quantities of silver in technical aluminum can be determined by TLC on the layer of microcrystalline cellulose after separation and concentration by coprecipitation with CdS. The chromatograms were developed by a solvent composed of butanol-methanol-water-nitric acid in the proportion 80 : 5 : 10 : 5 (v/v). Visualisation was made with hydrogen sulfide. After scanning the obtained spots, concentration of silver in the samples was calculated by comparison with reference spots.

Quantitative determination of lysolecithin and sphingomyelin in phospholipid mixtures by thin-layer chromatography as applied to the thymus of the fmfm mouse.
Lysolecithin and sphingomyelin may be readily separated from other phospholipids on thin-layer plates impregnated with silver nitrate using the solvent system chloroform-methanol-concentrated ammonium hydroxide 65:35:8. Quantitation is carried out by determining the phosphorus content of the developed bands. The minimum amount of phospholipid that can be quantitatively determined is that which ...
متن کاملSildenafil Determination in Various Matrices: A Review
Determination of sildenafil by various methods and in various media is reviewed in this paper. The methods used consist of ultraviolet (UV) spectroscopy, thin layer chromatography (TLC), and high-performance liquid chromatography (HPLC). These methods were used to determine the amount of sildenafil in pharmaceutical preparations, soft drinks, and biological liquids. HPLC was used for evaluation...
متن کاملAnalytical methods for determination of trans-C18 fatty acid isomers in milk fat. A review
This review describes analytical methods developed for the separation, identification and quantitation of trans-isomers of unsaturated fatty acids. Although these methods are applicable to a wide variety of food matrices, we have particularly emphasised the analysis of trans unsaturated fatty acids in milk fat. Various methods are described such as infrared spectroscopy, direct gas chromatograp...
متن کاملAn improved gas-liquid chromatographic method for the determination of fecal neutral sterols.
The analysis of fecal neutral sterols has been improved by use of a highly selective gas-liquid chromatography column packed with SP-2401. This chromatographic column allows separation of cholesterol and cholestanol and delta 5-5 alpha plant sterol homologs without employing silver nitrate thin-layer chromatography. Furthermore, there is no need to derivatize neutral sterols before injection. T...

A high performance liquid chromatography method was studied for determination of 18 ?-glycyrrhetinic acid in Glycyrrhiza glabra L. (licorice) extract. The operating condition were C-18 reversed phase column (VP-ODS, (250×4.6 mm, 5 mm)) at room temperature, acetonitril/phosphoric acid (3/1) as mobile phase, at flow rate of 0.6ml/min (0-8min), 0.4ml/min (8-20min) and UV detection at 230 nm. The...
