以有机基体改进剂、管壁原子化、热解涂层石墨管、峰面积积分吸收信号、Ｄ２灯或Ｚｅｅｍａｎ效应扣除背景，有效地控制和消除了海水基体对Ｃｄ、Ｃｏ、Ｃｒ、Ｃｕ、Ｍｎ、Ｎｉ、Ｐｂ等元素的干扰。在此前提下，用ＧＦＡＡＳ无标样分析法分析了实际海水样品中的痕量元素，与极谱法及间接火焰原子吸收法测得的结果相符，测得质控海水样品的结果与标准值亦很吻合，而且检出限和回收率都达到要求。 The effects of organic matrix modifier, wall atomization, pyrolytic coating of graphite tube, peak area integral absorption signal, D2 lamp or Zeeman effect on the background control of Cd, Co, Cr, Cu, Mn , Ni, Pb and other elements of interference. Under this premise, the trace elements in the actual seawater samples were analyzed by the GFAAS standardless analytical method in agreement with the results of polarography and indirect flame atomic absorption spectrometry. The results of the controlled seawater samples were compared with the standard values Also very consistent, and the detection limit and recovery have reached the requirements.
