| 英文摘要 | Laser ablation-atmospheric pressure glow discharge atomic emission spectrometry (LA-APGD-AES) was utilized to investigate the effect of matrix effects on the detection results of Cd and Pb in soil samples. Actual soil samples from different regions with large differences in major substances were selected. Under the laser energy of 60 mJ and laser pulse number of 20, the stable signal intensity and high sensitivity were obtained when the discharge distance was 14 mm, the gas flow rate was 130 mL/min, and the discharge current was 27 mA. This method was combined with the univariate calibration model to quantitatively detect Cd and Pb in four different matrix soils. The linear correlation coefficients (R-2) of Cd and Pb were >= 0. 99 and >0. 97, respectively. The relative errors of Cd and Pb measurement were 0. 4% -11. 8%. When the detection results were combined in the same calibration curve for analysis , the R-2 of Cd and Pb had slight change , and the relative errors of measurement were 3. 0% - 13. 2%. Moreover, the limits of detection ( LODs ) for Cd and Pb in different matrix soils had not change significantly. The detection results of all the verification values were agreement with values of inductively coupled plasma-optical emission spectroscopy (ICP-AES) . Overall, the detection results of Cd and Pb in complex matrix soils were less affected by matrix effects. |
