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%.

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%。
