研究应用氢化物发生-微波等离子体原子发射光谱法同时测定印刷品中的砷( As)、钡( Ba)、汞( Hg)、镉( Cd)、铬( Cr)、铅( Pb)、锑( Sb)、硒( Se)8种有害可迁移元素。文中对比了多模式进样氢化物发生法与单通道进样模式的方法检出限,并进行了重复性、加标回收率实验。方法检出限对比实验结果表明,多模式进样氢化物发生法的方法检出限范围为0.0007~0.0198μg/mL,优于仪器检出限范围0.0002~0.2308μg/mL;重复性实验结果表明,各元素检测相对标准偏差小于1.8%;加标回收率范围为92.0%~120.0%。综上所述,该方法具有较好的精密度和准确性,适合印刷品中有害可迁移元素的分析。
研究應用氫化物髮生-微波等離子體原子髮射光譜法同時測定印刷品中的砷( As)、鋇( Ba)、汞( Hg)、鎘( Cd)、鉻( Cr)、鉛( Pb)、銻( Sb)、硒( Se)8種有害可遷移元素。文中對比瞭多模式進樣氫化物髮生法與單通道進樣模式的方法檢齣限,併進行瞭重複性、加標迴收率實驗。方法檢齣限對比實驗結果錶明,多模式進樣氫化物髮生法的方法檢齣限範圍為0.0007~0.0198μg/mL,優于儀器檢齣限範圍0.0002~0.2308μg/mL;重複性實驗結果錶明,各元素檢測相對標準偏差小于1.8%;加標迴收率範圍為92.0%~120.0%。綜上所述,該方法具有較好的精密度和準確性,適閤印刷品中有害可遷移元素的分析。

The application of Hydride-microwave Plasma Atomic Emission Spectrometry ( MP-AES) to determine eight harmful migration elements , such as arsenic ( As ) , barium ( Ba ) , mercury ( Hg ) , cadmium ( Cd ) , chromium (Cr), lead (Pb), antimony (Sb), selenium (Se) in print at the same time was studied.The contrast experiment of method detection limit between the multimodal injection hydride method and the single channel sampling method , and repeatability experiments , the standard addition recovery rate experiments were carried out.The results of method detection limit experiments showed that the detection limit of multi -mode sample introduction system method was 0.000 7~0.019 8 μg/mL, which was better than the instrument detection limit which ranged from 0.000 2~0.230 8μg/mL.The results of repeatability experiments showed that the relative standard deviation was less than 1.8%of each element.The standard addition recovery rate of each element was in the range of 92.0% to 120.0%.The method was suitable for determination of the harmful migration elements in the print with its great simplicity and accuracy.
