Table 6 The concentrations of trace elements content in the test sample (Ptest) were determined using the CF-Ps-LIPS developed method, which considered plasma parameters fitting equations (plasma electron density and electron temperature) compared to the concentrations by ICP-OES.
Element | Concentration measured by ICP (ppm) | Unknown Concentration Calculations (S1) | |
|---|---|---|---|
Ne | Te | ||
Cd | 69.62 | 65.02 ± 0.93% | 75.80 ± 1% |
Zn | 145.33 | 136.94 ± 0.94% | 138.66 ± 0.95% |
Fe | 61.67 | 61.27 ± 0.99% | 61.27 ± 0.99% |
Ni | 149.53 | 149.87 ± 1% | 149.87 ± 1% |
