顺序注射氢化物发生－原子荧光光谱法测定化肥中砷、汞、锑和硒

A method for the determination of arsenic, mercury, selenium and antimony in fertilizer by sequential injection hydride generation-atomic fluorescence spectrometry (Hg-AFS) was established. Under the conditions proposed, detection limits of the As, Hg, Sb and Se are 0.15μg/L、0.061μg/L、0.046μg/L and 0.25μg/L. Recoveries of the As, Hg, Sb and Se have been proved to he 94.67%-106.81% in fertilizer. The mithod is suitable and practicable for the determination of As, Hg, Sb and Se in fertilizer.
