本文采用氢化物发生-银溶胶光度分析法探讨了GeH_4、AsH_3和H_2Se的性质,并利用共价氢化物气体分离柱分别建立了测定锗、砷时消除其它可生成氢化物元素干扰的简便、高效方法。测定1.0μg Ge(Ⅳ),5000μg As(Ⅴ)、Bi(Ⅱ)、Pb(Ⅰ)、1000μg Sb(Ⅱ)、Sn(Ⅰ)、500μg As(Ⅱ)和100μg Se(Ⅳ)、Sn(Ⅳ),Te(Ⅳ)不产生干扰。对砷的测定,其它共价氢化物元素的允许倍数分别为:Sb(Ⅱ)(5000)、Pb(Ⅰ)(5000)、Bi(Ⅱ)(5000)、Sn(Ⅰ)(1000)、Se(Ⅳ)(100)、Te(Ⅳ)(100)和Ge(Ⅳ)(15)。
In this paper, the properties of GeH_4, AsH_3 and H_2Se were discussed by hydride generation-silver sol photometry, and the determination of germanium and arsenic by covalent hydride gas separation column was carried out to eliminate the interference of other hydride-forming elements. method. (Ⅳ), 5000μg As (Ⅴ), Bi (Ⅱ), Pb (Ⅰ), 1000μg Sb (Ⅱ), Sn (Ⅰ), 500μg As (Ⅱ) and 100μg Se ), Te (Ⅳ) does not produce interference. For the determination of arsenic, the allowable multiples of other covalent hydride elements are Sb (Ⅱ) (5000), Pb (Ⅰ) (5000), Bi (Ⅱ) (Ⅳ) (100), Te (Ⅳ) (100) and Ge (Ⅳ) (15).
