| titleOfInvention | The measuring method of cobalt contents in a kind of tobacco lining paper |
| abstract | The measuring method of cobalt contents in a kind of tobacco lining paper, after tobacco lining paper sample is added nitric acid, hydrochloric acid, hydrofluoric acid, hydrogen peroxide by the method, carry out micro-wave digestion under elevated pressure conditions, solution to be measured is obtained after then carrying out catching up with the fixed appearance of acid, dilution, liquid to be measured is imported icp ms through hydrofluoric acid resistant cross intersection spraying gun, adopts the content of cobalt in level Four bar collision cell technical measurement sample. The method comprises the selection of kind and the consumption clearing up reagent, clears up the optimization of pressure, and icp ms adopts collision cell pattern (kinetic energy screens KED technology) to eliminate matrix interference, the selection of isotropic substance and internal standard element. Through optimize after detection method have clear up abundant, highly sensitive, the rate of recovery and repeatability good, the advantages such as the matrix interference that a large amount of aluminum ion brings can be overcome, it is suitable for tobacco industry and cobalt in tobacco lining paper is carried out quantitative assay by tobacco lining paper manufacturing enterprise technician, fills up the blank of this technical field. |
