摘要
目的建立用石墨炉原子吸收法直接测定尿锰的方法。方法尿样用稀硝酸稀释后,采用热解涂层石墨管,塞曼扣背景,石墨炉原子吸收法直接测定尿中锰含量。结果方法的检测限为0.03 ng/ml,回收率为96.5%～106.3%,试验的精密度RSD为5.9%～12.6%。结论该方法具有快速、准确、灵敏度高等特点,适用于尿中锰含量的测定。
[ Objective] To establish a method for determination of manganese in urine by graphitefurnace atomic absorption spec- trometry （ GFAAS }. [ Methods ] The sample was diluted directly, pyrolytic coating graphite tube and Zeeman background correction were adopted, and manganese content in urine was measured by GFAAS. [ Results ] The detection limit was 0. 03 ng/ml, recovery rate was 96.5% - 106.3% and the Test precision RSD was 5.9% - 12. 6 %. [ Conclusion] The method is rapid, accurate, and with high sensitivity can be recommended for the determination of manganese content in urine.
