Abstract
In accordance with the requirements of the reference materials technical specifications, refer to some countries’ existing standards of chemical composition of copper Cathode products, design the chemical composition of each reference materials. Using proper methods of batching, smelting technique and extrusion processes etc., developed a set of reference materials of copper Cathode. Determine the content of the various elements using a variety of methods by several laboratories. These samples are mainly used for the determination of Pb, Fe, Bi, Sb, As, Sn, Ni,, Zn, P, S in copper cathode and parts of copper by photoelectric direct reading spectrometry, plasma spectroscopy and various methods of chemical analysis, these samples can also act as control samples for the control analysis of the relevant elements separately. The series of reference materials have advantages of accurate value, good uniformity and precision and linear, more reasonable distribution of elements.
