Toy material can be transferred elements of antimony, arsenic, barium, cadmium, Determination of chromium, lead, mercury and selenium Inductively coupled plasma mass spectrometry WARNING - Personnel using this standard should have practical experience in formal laboratory work. This standard does not indicate all possible security questions question. It is the responsibility of the user to take appropriate safety and health measures and to ensure compliance with the conditions set forth in the relevant national regulations.

1 Scope

This standard specifies the determination of traceable antimony, arsenic, barium, cadmium, chromium, lead, mercury and selenium in toy materials by inductively coupled plasma mass spectrometry. Measuring method. This standard applies to GB 6675 applicable to all the toys in the transferable elements of antimony, arsenic, barium, cadmium, chromium, lead, mercury, selenium Determination. The limits of detection of this standard method. the use of non-online added, antimony, arsenic, barium, cadmium, chromium, lead, mercury, selenium detection limit 0.25mg/kg; internal standard with online added, antimony, arsenic, barium, cadmium, chromium, lead, mercury, selenium detection limit of 0.05mg/kg.

2 normative reference documents

The terms of the following documents are hereby incorporated by reference into this standard. Whichever is the date of the reference file, which is followed by all (Excluding corrigenda) or revisions do not apply to this standard, however, encourage the parties to reach an agreement under this standard Whether to use the latest version of these files. For undated references, the latest edition applies to this standard.

3 principle

After the sample is processed, the test solution is atomized by the carrier gas into the inductively coupled plasma torch flame, under the action of the high temperature of the plasma Product to solvate, atomize, ionize into the mass spectrometer, mass spectrometer according to the mass ratio of the material qualitative. For a certain mass-to-charge ratio The signal strength CPS (countpersecond) is proportional to the concentration of the element to be measured in the sample extract, and the sample is measured by measuring the CPS The content of each element to be measured in the extract.

4 reagents and materials

4.1 used glassware are required to use 20% nitric acid soak overnight, washed repeatedly with water. All test water is GB/T 6682 Prescribed first class water. 4.2 nitric acid (ρ20 = 1.42g/mL). excellent grade pure. 4.3 nitric acid solution (volume fraction of 2%). take 20mL nitric acid (4.2), diluted with water to 1000mL. 4.4 hydrochloric acid solution. c (HCl) = (0.070 ± 0.005) mol/L. 4.5 Scandium, germanium, yttrium, indium, rhenium mixed standard solution (10.0mg/L), the use of standard solution (nitric acid or hydrochloric acid medium) prepared into the required concentration. 4.6 standard stock solution of antimony, arsenic, barium, cadmium, chromium, lead, mercury and selenium, the standard solution (nitric acid or hydrochloric acid medium) Concentration (antimony, arsenic, cadmium, chromium, lead and mercury concentrations were 100.0mg/L, barium and selenium concentrations were 1000mg/L). 4.7 antimony, arsenic, barium, cadmium, chromium, lead, mercury, selenium mixed standard liquid. 10.00mL of antimony, arsenic, cadmium, chromium, lead, mercury, barium and selenium (4.6), placed in a 100 mL volumetric flask, diluted with nitric acid solution (4.3) to a graduated volume and mixed. Prepared into the following concentrations
