  • 摘要: 本文提出一种新的混合改进剂(锆+酒石酸),能有效消除高氯酸、硝酸以及各种基体的干扰、比较了各原子化温度时理论和实验特征量,使热解石墨管有可能用于石墨炉原子吸收法测定各种环境样品中的锡,准确度和精度优于8%.
    Abstract: A new mixed chemical modifier (Zr + tartaric acid) and pyrolytic coating graphite tube were selected for the determination of tin in environmental samples. The new modifier was used for elimination of matrix effect from HClO4, HNO3 and other matrices. A comparison of experimental and calculated characteristic mass was made. This paper shows that the modern graphite furnace technique provides the possibility of Sn determination in a variety of complex matrices within 8% accuracy.
