1 Scope

This section YS/T 3015 specifies the method for determination of loaded carbon in copper, iron, calcium and magnesium content. This section applies to the determination of gold contained in copper on carbon, iron, calcium and magnesium content. Measurement range. 0.010% to 2.00% copper; iron ~ 0.010% 1.00%; 0.050% to 2.00% Ca; Mg 0.010% to 0.50%.

2 Method summary

The sample was burning ashed with hydrochloric acid, nitric acid to dissolve the residue. In dilute hydrochloric acid medium, in inductively coupled plasma atomic emission spectroscopy election Under certain conditions, determine the mass concentration of each element in the test solution, according to the standard curve method to calculate copper, iron, calcium and magnesium content.
