| Abstract: | Pb and Mn in an effective state of environment in soil were simultaneously determined by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). The soil sample was digested with HNO3-HCl-HClO4, and the ICP-AES experimental conditions were optimized. The axial observation position and the following experimental settings were used: the wavelengths selected for Pb 220.353 nm and for Mn 257.610 nm, delay time 30 s, RF power 1300 w, nebulizer flow rate 0.8 L/min, and pump flow rate 1.5 mL/min. The results showed that ICP-AES was simple and reliable, and could be used for analyzing Pb and Mn in an effective state of environment in soil and evaluating the pollution level and the migration of Pb and Mn in soil. |
