A simple and rapid method for the determination and characterization of chemically bonded ligands on reversed-phase packing materials is described. The method consists of cleavage with aqueous concentrated hydrofluoric acid and analysis of the reaction product by GC, NMR and mass spectrometry. It is confirmed from (13)C-NMR spectra that the structure of the(More)
In the spectrophotometric determination of aluminium and iron with ferron (7-iodo-8-quinolinol-5-sulphonic acid, H(2)L), the addition of cationic surfactants greatly improves the linearity of the calibration curve and widens the useful pH range. The effect of cetyltrimethylammonium chloride (CTMAC) on the stepwise stability constants (K(1),K(2) and K(3)) of(More)
At nuclear emergency accident such as inhalation intake of alpha nuclide, an indispensable nasal swab method has not been used for the precise internal dose estimation. One of the reasons is uncertainty in its radiation measurement, so that precise measurement with alpha spectrometry was examined for filter samples simulating nasal swab. It was confirmed(More)
