| 中文摘要: |
| 试验了集恒温平台石墨炉 (ST PF) 于一体的纵向塞曼效应背景校正, 最大功率升温, 钯作为基体改进剂和峰面积积分( A - s )测定废水中低含量锡的新方法。测定结果表明, 锡含量在0 μ g/L~ 100μ g/L范围内呈良好的线性关系, 检测限(3σ)3.5×10 - 11 g, 特征量为9.1×10 - 11 g, 相对标准差小于6%, 回收率在91% ~ 107% 之间。 |

Itcombined stabletemperature platform graphitefurnace, undertook correction with verticalZeeman effect background,took palladium as matrix modifier and peak areaintegral. Theresultsindicatedthatthere were a goodlinearrelationship whentheconcentrationof Tin withinthelimitof0μg/L~ 100μ g/L,the detectionlimit(3σ)was3.5×10- 11 g,trait quantity was9.1×10 - 11 g, relativestandard deviation waslessthan 6%,recoveryrate was within 91% ~ 107%. |
