摘要
提出了在乙醇-乙醇胺溶液中,用非水滴定法简便快速测定地质样品中的总碳的方法。经对国家一级标准物质分析,结果准确可靠,相对标准偏差(RSD,n=12)ω小于3.8%,方法检出限为0.011%。
The author promotes the use of non-water titrimetry to determine the total carbon briefly and straightforwardly in the solution of ethanol and ethanol amine. Through matter analyses of national class one criteria, the results are accurate and reliable with a relative standard error of （RSD,n = 12） to 〈3.8% and detection limit of 0. 011%.
