Elemental Elemental Dissolution of Plastics and Their Products Simultaneously Measured Method of inductively coupled plasma mass spectrometry1 ScopeThis standard specifies the simultaneous determination of the inductance of lead, cadmium, chromium, arsenic, mercury, antimony, zinc, germanium, nickel, selenium and barium in plastics and their products Coupled Plasma Mass Spectrometry. This standard applies to plastic and its products Determination of lead, cadmium, chromium, arsenic, mercury, antimony, zinc, germanium, nickel, selenium and barium dissolution.2 Normative referencesThe following documents for the application of this document is essential. For dated references, only the dated version applies to this article Pieces. For undated references, the latest edition (including all amendments) applies to this document. GB/T 602 chemical reagent impurity standard solution preparation GB/T 6682 analytical laboratory water specifications and test methods GB/T 5009.156-2003 Food packaging materials and their products immersion test methods General3 method summaryThe sample is soaked in 4% acetic acid solution, soaked into the resulting solution by adding internal standard elements into the inductively coupled plasma mass spectrometer, in the plasma Under the action of high temperature, desolvation, atomization, ionization into the mass spectrometer detector, within a certain range, the measured elemental ionic strength and containing Is proportional to the amount, compared with the standard series quantitative.4 reagentUnless otherwise specified, only excellent grade pure reagents are used in the analysis. The experimental water shall meet the requirements of Class I water specified in GB/T 6682. 4.1 Glacial acetic acid (ρ = 1.05g/mL). 4.2 acetic acid solution (4%) Take 40mL glacial acetic acid (4.1), add water to 1000mL, mix. 4.3 Standard stock solution of lead, cadmium, chromium, arsenic, mercury, antimony, zinc, germanium, nickel, selenium, barium and gold (1000mg/L) Prepared according to GB/T 602 regulations. 4.4 Lead, cadmium, chromium, arsenic, antimony, zinc, germanium, nickel, selenium and barium The standard standard stock solution (4.3) was diluted serially with acetic acid solution (4.2) to prepare serial concentrations of 5μg/L, 10μg/L, 20μg/L, 50μg/L, 100μg/L mixed standard working solution. 4.5 Mercury standard working solution. Mercury and gold standard stock solution (4.3) were separately aspirated and diluted stepwise by acetic acid solution (4.2) to prepare gold concentration The mercury standard working solutions were 0.5μg/L, 1μg/L, 2μg/L, 5μg/L and 10μg/L, respectively. 4.6 gold standard working solution. Draw gold standard stock solution (4.3), acetic acid solution (4.2) step by step diluted to prepare a concentration of 10mg/L Gold standard working solution. 4.7 Scandium, indium and bismuth standard stock solution (10mg/L), respectively, using certified standard solution or GB/T 602 provisions. 4.8 Scandium, indium and bismuth internal standard solution (10μg/L) were scud, indium and bismuth standard stock solution (4.7) 1mL, diluted with acetic acid solution (4.2) To 1000 mL, the concentration of this solution is 10 μg/L. ...... |
