炭管富集FAAS法快速测定水中痕量锰

Quick Determination of Trace Manganese in Water by FAAS of Carbon Tube Enrichment

本文用微型活性炭管富集结合原子吸收富解仪FAAS法测定水样中痕量锰,使整个测定标的富集解吸过程通过仪器自动化完成,分析一个样品仅需2min即可完成。实验结果表明相对标准偏差1.2％-62％,用本法测定8904M。标准物质相对误差0.8％。

This paper presents a method of small carbon envichment with enrichment and absorptive separation of AAS instrument for the determination of trace manganese in water by FAAS. Determination of manganese of enrichment and absorptive separation are finished voluntarily through instrument. It only take two minutes to analyze a sample. It is shown taht:the relative standard deviation fell into 1. 2 % - 6. 2 % the relative dehation for detecting 8904M9 standard substance is 0. 8 %.
