| 摘 要： | 采用横向加热石墨炉原子吸收法测定儿童血液和头发中的铅和铝，以磷酸二氢铵和硝酸镁或硝酸镁作基体改进剂，提高了测定铅的灰化温度和灵敏度，消除了基体干扰和记忆效应。方法简便、快速、准确度高。铅和铝的特征量分别为：2.3×10-11 g和2.2×10-11 g，相对标准偏差为3.0%～11.4%，回收率为96%～110%。

| Abstract: | Pb and Al in blood and hair of child were determined by transverse heated graphite furnace atomic absorption spectrometry with NH4H2PO4 and Mg(NO3)2 as a modifier, which enhanced the temperature of ashing, eliminated the matrix interference and memorial effect. The method is rapid, simple and accurate. The characteristic mass of the method was 2.3 x 10(-11) g and 2.2 x 10(-11) g for Pb and Al respectively. The relative standard deviation of Pb and Al was 3.0% and 11.4%, respectively, and the recovery was 96%-102%. |
