摘要
本文建立了一种顺序注射氢化物发生 -原子荧光光谱法测定化肥中 As、Hg、Sb、Se含量的方法。在最佳条件下 ,As、Hg、Sb和 Se的检出限分别为 0 .1 5μg/ L、0 .0 6 1μg/ L、0 .0 4 6μg/ L、0 .2 5μg/ L。测定化肥中 As、Hg、Sb和 Se,回收率均在 94 .6 7%— 1 0 6 .81 %之间。该方法用于检测化肥中 As、Hg、Sb和 Se具有很好的可行性和实用性。
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 be 94.67%—106.81% in fertilizer.The mithod is suitable and practicable for the determination of As,Hg,Sb and Se in fertilizer.
