火焰原子吸收分光光度法测定尿锰的方法研究

Flame atom absorption spectrophotometric method for determination of urine manganese

目的：探索尿锰检测的新方法。方法：采用原子吸收火焰法直接测定,同时在样品消化时采用了浓氨水沉淀,又用250 m l凯氏氮瓶消化法。结果：回收率：90.0%～99.5%;相对标准偏差为2.4%;方法检出限为0.0190 mg/L。结论：该法样品消化简单,回收率高,适宜大批量样品检测。

Objective：To explore a new method for determination of urine manganese.Methods：Uses the atomic absorption flame law immediate determinant,simultaneously when sample digestion has used the strong ammonia water precipitation,also uses the 250 ml kelvin nitrogen bottle digestion law.Results：Returns-ratio： 90.0%~99.5%.The relatively standard deviation was 2.4%.The detection limit was 0.0190 mg/L.Conclusion：This method is simple and accurate.
