Abstract

[Objective]To establish the method of analyzing the manganese in the whole blood by graphite furnace atomic absorption spectrometry(AAS) directly and rapidly.[Methods]The samples which were digested and emulsified by sample diluent of nitric acid and TritonX-100 were detected in AAS with a automatic sampling system,using deuterium lamp for background correction.[Results]The linear range of the method was 0 ～3.0 μg/L,correlation coefficient was 0.9994,RSD was 1.1% ～7.7%,standard recovery was 93.7% ～ 101.0%,the detection limit was 1.2 μg/L.[Conclusion]The method has reliable accuracy and precision,does not have to be digested,and can be used to determine manganese in whole blood simply,rapidly and feasibly.
