摘　　要：按照《纺织品重金属的测定第4部分:砷、汞原子荧光分光光度法》方法测定羊毛纤维及织物中重金属汞的残留量。通过对方法的检出限、精密度和准确度的研究与分析,证明实验室使用该方法的可靠性和准确性。结果表明,方法的检出限为0.001 mg/kg,精密度为3.1%,准确度为96.0%。证明该方法的灵敏度高,重现性好,结果精确,能满足实验室的检测要求。An Hg residue is determined according with ＂Textiles-Determination of heavy metals-Part 4： Arsenic and mercury-Atomic fluorescence spectrophotometry＂. Through researching and analyzing determinate limits, precision and accuracy of the method, to prove how high the reliability and accuracy of the method is in the laboratory. The results showed that the determinate limits was 0.001 mg/kg, the precision was 3.1%, and the accuracy was 96.0 %, which demonstrates that determining Hg content of this method can meet the testing requirements because of its high sensitivity, good reproducibility and accurate results.
