3 Terms and definitions

There are no terms or definitions that require definition in this document.

4 Principle

The sample was acidified and measured using an inductively coupled plasma emission spectrometer. The target elements were gasified, ionized, and excited in the plasma torch. It emits and radiates characteristic spectral lines. Within a certain concentration range, the intensity of its characteristic spectral lines is proportional to the concentration of the element.

5 Reagents or materials

Unless otherwise specified, only reagents of confirmed high purity were used in the analysis, and the water used was first-grade water as specified in GB/T 6682 or water with Its purity is equivalent to water. 5.1 Nitric acid (ρ20=1.42 g/mL). 5.2 Hydrochloric acid (ρ20=1.19 g/mL). 5.3 Sulfuric acid (ρ20=1.84 g/mL). ......
