Resumen
The method is applicable to Zn 99,995, Zn 99,99 and Zn 99,95. Although these types of zinc do not normally contain any thallium or indium, these two elements, if present, can interfere in this determination. The method is suitable for the determination of lead and cadmium contents between 0,001 and 0,05 %.
