3 Method summary
Sample using a specific concentration of hydrochloric acid, so that analyte migration under certain conditions, after filtering the resulting solution was added to the standard sample, conducted
By ICP-MS. In mass to charge ratio of the strength of its quantitative relationship element concentration was measured in a sample of aluminum, antimony, arsenic, barium, boron, cadmium, chromium, cobalt, copper,
Migration of lead, manganese, mercury, nickel, selenium, strontium, tin, zinc and other elements.
4 Reagents and materials
Unless otherwise indicated in the analysis using only recognized as pure class distinctions or through sub-boiling distilled chemical reagents, laboratory water match
GB/T 6682 provisions of secondary water.
4.1 of concentrated hydrochloric acid (37% concentration).
4.2 hydrochloric acid solution (0.07 ± 0.005mol/L).
4.3 concentrated nitric acid (65% concentration).
4.4 nitric acid solution (28 volume). Take 20mL of concentrated nitric acid (4.3) was slowly added 80mL of water.
4.5 standard stock solution. aluminum, antimony, arsenic, barium, boron, cadmium, chromium, cobalt, copper, lead, manganese, mercury, nickel, selenium, strontium, tin, zinc standard solution according to GB/T 602 Party
Preparation method, or directly using standard element solution is a solution of the certificate within the validity period, the concentration of standard stock solution are
1000μg/mL.
4.6 mixed standard working solution. serial dilution of aluminum, antimony, arsenic, barium, boron, cadmium, chromium, cobalt, copper, lead, manganese, nickel, selenium, strontium with hydrochloric acid solution (4.2),
Tin, zinc standard stock solution to prepare a series of concentrations of mixed standard working solution, the concentration of standard working solution see Appendix A, Table A.1. standard
Working solution required for immediate use.
4.7 internal standard stock solution. germanium, indium, bismuth concentration was 1000μg/mL.
4.8 internal standard working solution. with a hydrochloric acid solution (4.2) was diluted stepwise germanium, indium, bismuth internal standard stock solution, formulated in a concentration of 5μg/L internal standard mixing
Working solution, select the different elements of the internal standard elements see Appendix A in Table A.2.
