In inductively coupled plasma optical emission spectrometry (ICP-OES), the presence of carbon in matrix strongly affects (positively and negatively) signal atomic lines. However, ionic lines is mostly unaffected by this concomitant. The goal work to gain insight into origin effects on ICP-OES. To end, a total 3608 (i.e., 1755 1853 lines) 62 elements (Ag, Al, As, Au, B, Ba, Be, Ca, Cd, Ce, Co, C...
