| 摘 要： | 用酸消解法与干灰化法分别处理广西3个锰矿废弃地的10种植物样品,并用原子吸收分光光度计测定其Pb、Cd和Cu的含量。结果表明,处理方法对Cu和Pb测定结果有明显影响,而对Cd则影响不大。在测定植物组织Cu含量时,采用干灰化法较好;测定Cd含量时,两种方法均可采用。在叶组织Pb测定时,两种处理方法无明显分别,但木质组织Pb测定时采用干灰化法更为理想。

| Abstract: | Ten plant samples from three Mn mine wastelands in Guangxi were collected and determined for Pb,Cd and Cu concentrations by using acid digestion and dry ashing pretreatment respectively.The results indicated that the two pretreatment methods had a significant effect on the Cu and Pb levels,but no influence on Cd.For the determination of Cu,dry ashing is better;for Cd,either of the two pretreatments can be used;for Pb,dry ashing is preferable for the wooden parts while both are applicable for the leaf tissues. |
