| 中文摘要 |
| 介绍了碳纤维束汞膜微电极的制作过程,研究此电极的伏安特性,用阳极溶出伏安法测定汽车尾气中的铅含量,确定适宜的实验条件。该法简便,快速,灵敏度高,重现性好。检出限为0.1ng·ml-1,线性范围1.0-20ng·ml-1,相对标准偏差9.4%。 |
| 英文摘要 |
| In this paper,the preparation for carbon fiber beam mercury film microelectredes was described.The electrode voltammetric properties were investigated.Lead content from automobile exhaust was determined using anodic stripping voltammetry.The suitable experimental conditions were assigned. This technique is simple,quick,with high sensitivity and fine reproducibility.The detection limit is about 0.1 ng·ml-1,the linear range is 1.0ng·ml-1-20 ng·ml-1.The relative standard deviation is 9.4%. |
