3 method summary
The sample was dissolved in nitric acid and hydrochloric acid, filtered, and the filtrate was stored as a main liquid. The residue was alkali-melted and acid-leached, and the resulting solution was combined with the main solution to make a constant volume. will
The test solution is introduced into an inductively coupled plasma atomic emission spectrometer to calculate the content of the element to be tested.
