摘要: 家具漆涂层经刮取、粉碎、过筛后在微波消解装置中用浓硝酸及过氧化氢消化,氢氟酸络合,所得溶液定 容后用石墨炉原子吸收光谱法测定。该方法的线性范围为 0~80μg/L,相对标准偏差 1.25% ~3.47%,检出限为 0.30 μg/L,回收率 92.1% ~107.5%。

Abstract: The furniture paint films was scraped off,then crushed,gridled,and digested with HNO3 and H2O2 in a microwave oven.The sample solution was diluted to specified volume and used for the GF- ASS determination.Linearity was kept in the range of 0~80μg/L of lead concentration,RSD1.25% ~ 3.47% detection 0.30μg/L and recovery 92.1% ~107.5%.
