In this paper, a comparison of two different analytical methods is described based on element composition. The elements Al, Sr, Li, Cu, Pb, Cr, V, and Ni were directly determined in water samples using inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS). The ICP-OES and ICP-MS data were compared and correlation plots were constructed. The correlation between the two methods of analysis varied, with the maximum correlation of 0.999 observed for Pb, and the minimum correlation of 0.907 observed for Sr. The order of the distribution coefficients for the eight metals determined was: Pb > Cu > V > Ni > Al > Cr > Li > Sr.
