ISO DIS 13547-2

Description / Abstract: This International Standard specifies an acid digestion and inductively coupled plasma atomic emission spectrometric (ICP-AES) method for the determination of the mass fraction of arsenic in copper, lead, zinc and nickel sulfide concentrates as follows:

a) For copper sulfide concentrates, the method is applicable to the determination of mass fractions of arsenic from 0,05% to 2,0%;

b) For lead sulfide concentrates, the method is applicable to the determination of mass fractions of arsenic from 0,05% to 1,0%;

c) For zinc sulfide concentrates, the method is applicable to the determination of mass fractions of arsenic from 0,05% to 0,6%;

d) For nickel sulfide concentrates, the method is applicable to the determination of mass fraction of arsenic from 0,05% to 1,0%.
