The optimal conditions were
investigated to the determination of W, Sn, As, Bi element in ores by inductively coupled
plasma atomic emission spectrometry. The influence of major
elements in matrix of samples were studied. Then the suitable condition
had been found for establishing a specific process to identify these elements.
Based on this principle, we study the optiman condition of the equipment as
well as the factors which impact on spectrum of W, Sn, As, Bi elements in
ore samples. From these, the reference lines and specified procedure can be
established to determine concentration of W, Sn, AS, and Bi by ICP-OES method.
