For the development of 99Mo production procedure,both of recovery yield of 99Mo and the removal of other impurities should be taken into account.Anion exchange chromatography is usually employed for purification of 99Mo from fission products.AG1-X8resin is a kind of strong中国原子能科学研究院...
The preparative benchtop separation procedure employs elution with HCl through a BioRad AG1-X8 anion-exchange resin column, and fraction collection. The importance of the separation of the 232 U isotope from daughter products, characterized by high recovery, is illustrated by liquid scintillation ...
Rather complicated, two-step procedures are still widely used, because several major elements (e.g., P, Ti, Al and Fe) accompany the analyte when conventional ion-exchange chromatography techniques are used [9], [10], [17], [18], [19]. Although a single column procedure, based on ...
Typically, the sample containing NaOAc and NaOH is passed through a cation exchange column (Dowex 50WX8-100, ammonium form) and then ammonium acetate is removed from the eluted analyte by lyophilization. MALDI-TOF MS (matrix-assisted laser desorption/ionization-time of flight mass spectrometry) ...
An acetic acid solution of Re-188 perrhenic acid is obtained by subsequent on-line passage of the generator eluant through a DOWEX AG 50Wx8 (200-400 mesh, H{sup +} form) column. Since acetic acid is not ionized (< 0.001%) at this pH (< pK{sub a} = 4.76) the perrhenate anion...
ples containing AsB may be done on other anion-exchange columns (e.g. Supercosil LC-SAX 1 [9]; Shodex Asahipak ES- 502N 7C [17], cation-exchange columns (e.g. Hamilton PRP X-200 [18]) or a coupling of an anion-exchange column with a cation-exchange column [19]. However, thes...
The column was packed with strongly basic anion-exchange resin (AG 1-X8). Experimental conditions including pH of the sample solution, eluent, flow rate of eluent, oxidation states of arsenic and competing anion ions were studied. Compared with the conventional continuous hydride generation ICP, a...

Sulphate preconcentration by anion exchange resin in flow injection and its turbidimetric determination in waterA preconcentration procedure was established for sulphate determination in rain waters at the mg/l level, employing a small column packed with the AG1-X8 (200–400 mesh) anionic resin ...
The separation of cadmium from indium, zinc and many other elements is considerably improved by eluting these elements with 0.1 M hydrobromic–0.5 M nitric acid solution from a column of AG1-X8 resin. Cadmium is retained very strongly and can be eluted with 2 M nitric acid or 1 M ammonia...
