【摘要】 目的:建立快速有效的尿样消解方法和准确灵敏的石墨炉原子吸收检测程序。方法:将尿样用硝酸和高氯酸消解后,石墨炉原子吸收法测其中铜锰镉含量。结果:铜锰镉的检出限分别为0.05ug/L,0.06ug/L,0.028ug/L;RSD分别为0.50%,0.55%,0.57%;回收率分别为98.0%～102%;94.2%～107.5%;98%～104%。结论:该法灵敏、准确、可靠、检出限低,可适用于实验室常规检测。更多还原

【Abstract】 Objective:To establish a rapid and effective method of person Urine digestion and accurate and sensitive atomic absorption detection method.Method:Using graphite furnace atomic absorption spectrophotometry to measure the content of copper and manganese and cadmium in person Urine after digestion.Results:The detec- tion limits of copper,manganese and cadmium are 0.05ug/L,0.2ug/L,0.05ug/L; RSD are 0.50%,0.55%,0. 57%。Recovery rates are 98.0%～102%;94.2%～107.5%;98%～104%respectively.Conclusion:The meth- od is sensitive,accurate,reliable,low detection limits,suitably in laboratory convention examination.更多还原
