Possibilities of High Resolution Inductively Coupled Plasma Optical Emission Spectrometry in the Determination of Trace Elements in Environmental Materials

Table 2

Quantitative values for line interferences [𝑄_𝐼𝐽(𝜆_𝑎)] and wing background interference [𝑄_𝑊𝐽(Δ𝜆_𝑎)] in the determination of trace of elements Zn, Cd, Sb, Cu, Mn, Pb, Sn, Cr, U, and Ba. Interferents: Al, Ca, Fe, Mg, and Ti. The data listed under the wavelength of the prominent lines refer to background equivalent concentrations in pure solvent (BEC) and detection limits in pure solvent (𝐶_𝐿).
