基体改进剂应用于服装附件可释放镍含量测定的研究

摘要

Based on detecting the nickel released from garment accessories with graphite furnace atomic absorption spectrometry,it was found that there was a serious problem of matrix interference.Through the studies on matrix modifier selection and dosage selection, the problem was solved.The results showed that the standard recoverv rate was 95.8％～101.6％, the accuracy was 1.02％～　3.62％.This method was suitable for the detection of nickel content released from garment accessories.%通过对石墨炉原子吸收法测定可释放镍含量的研究发现,用石墨炉法测定纺织品中可释放镍含量存在严重的基体干扰问题.对基体改进剂的选择和用量等进行研究,该问题得到解决.该方法加标回收率为95.8%～101.6%,精密度为1.02%～3.62%,适用于纺织品附件中可释放镍含量的测定.
