摘要
研究了氢化物发生-原子荧光光谱法测定普碳钢、低合金钢中的锡,试验了酸介质、载气流量、还原剂用量测定的影响,并选择出最佳工作条件。锡的检出限为0.248μg/L,相对标准偏差分别为4.44%、1.02%。
The paper reports the determination of Sn in the carbon steel and low alloy steel. The influences of different acid mediums, reductant and flow - rate of the carrier gas on the determination of Sn are studied and optimized. The limit of detection is 0.248ug/L and its RSD is 4.44%, 1.02% respectively.
