| Abstract: | Wavelet transform was applied to the processing of noisy signal in ICP AES.The noise was successfully eliminated and smooth spectra were obtained.The ratios of signal to noise were enhanced,the accuracies of analytical results and the detection limits were improved. |
| Keywords: | Wavelet tranform ICP-AES Noise process |
