| 摘 要： | 讨论了用原子吸收光度法测定土壤中铜、锌、铅、镍和锰。通过硝酸-氢氟酸-高氯酸以及硝酸-盐酸-过氧化氢体系消解液对土壤样品消解,选择出微波最佳消解条件。对硝酸-氢氟酸-高氯酸体系消解液和硝酸-盐酸-过氧化氢体系消解液进行消解对比试验,发现前者将土壤样品中的铜、镍和锰完全消解,后者能将样品中的锌和铅消解完全。微波消解土壤和传统电热板消解在测定前都需将消解液中剩余的酸赶尽,但与传统电热板消解相比,微波消解操作简便快速,可提高工作效率。

| Abstract: | Detecting Cu,Zn,Pb,Ni and Mn in soil with microwave digestion-AAS was discussed in this paper.The best digestion condition was found by using HNO_3-HF-HClO_4 and HNO_3-HCl-H_2O_2 to digest soil sample.It was indicated that the former can digest Cu,Ni and Mn in the soil completely,and the latter can digest Zn and Pb completely and respectively.Both microwave digestion and traditional electric hot plate digestion,the acid needed to be removed completely before detecting,and microwave digestion was more simple and efficiency than traditional electric hot plate digestion. |
