正相液体色谱法测定ppt量级的硒
- SELENIUM DETERMINATION AT PPT LEVELUSING HPLC-FLD SYSTEM
- 摘要:硒作为生命必需的微量元素,其有关研究报告日见增多。在我国,已经报道了由区域环境低硒引起的大骨节病、克山病、以及区域性癌症。相关研究工作包括我国低硒带的成因、硒的生物地球化学循环、地方病病因的探讨。
- Abstract:A normal-phase HPLC with fiuorimetric detector has been developed for selenium determination at pg level. For a sample volume of 20 ml, the working range of the technique is 0-0.5 ppb, and the detection i-mit is 500 fg. The procedure can be applied to selenium speciation of environmental samples with concentrations of 0.001 ppb for Se(IV) and 0.005 ppb for Se(V or total selenium.
