摘　　要：采用偏振塞曼原子吸收法，以Ｃａ作基体改进剂，注入热解涂层石墨管中，直接测定用ＯＰ溶液稀释血液样品中的痕量铝，有效地消除了血液基体的干扰，克服了铝的记忆效应，从而提高了方法的测定灵敏度、重现性和准确度．A method of direct determination of trace Al in blood diluted with OP solution by polarization Zeeman atomic absorption spectrometry. using Ca as matrix modifier is presented. The method has removed effectively interference of blood matrix. overcome memory effect of aluminium.and obtained satisfactory sensitivity.repeatability and accuracy.
