GB/T 6682 Analysis Laboratory Water Specifications and Test Methods
3 Terms and Definitions
There are no terms and definitions that need to be defined in this document.
4 Principles
After the sample was dissolved in nitric acid and hydrochloric acid, the solution was fixed to volume and then weighed (accurate to 0.0001g), using yttrium as the internal standard element, using inductively coupled plasma
The daughter atomic emission spectrometer was used to measure the intensity of the characteristic spectral line of the element to be tested in the solution, and the content of zinc, cadmium and cadmium in the sample were calculated through the standard curve.
content.
5 Reagents or materials
Unless otherwise specified, only reagents confirmed as analytical grade and laboratory secondary water in accordance with GB/T 6682 are used in the analysis.
5.1 Hydrochloric acid (ρ=1.19g/mL).
5.2 Nitric acid (ρ=1.42g/mL).
5.3 Hydrochloric acid (1 10).
5.4 Zinc standard solution. Weigh 0.10g of metallic zinc (wZn≥99.99%) (accurate to 0.0001g) into a 250mL beaker, add 15mL
Hydrochloric acid (5.1), 5 mL of nitric acid (5.2), cover with a watch glass, heat at low temperature until completely dissolved, remove, cool to room temperature, rinse the surface with a small amount of water
Transfer the test solution to a pre-dried and weighed 250mL volumetric flask (m0), dilute it with water to the mark, and weigh the mass (m1) (accurate to
0.001g), mix well, 1g of this solution contains about 400μg zinc.
5.5 Cadmium standard solution. Weigh 0.10g metal cadmium (wCd≥99.99%) (accurate to 0.0001g) into a 250mL beaker, add 15mL
