| 摘 要： | 样品用硝酸溶解,在氨性溶液中,以氢氧化铁和氢氧化镧作载体富集锑,并与铜分离。在稀盐酸介质中,用空气-乙炔火焰,于原子吸收分光光度计上,217.6nm波长处测其吸光度,方法的相对标准偏差为0.19%,该方法简捷、快速。

| Abstract: | Electrolytic copper was dissolved with HNO_3.In ammonia solution,antimony would be preconcentrated with its loading body of Fe(OH)_3 and La(OH)_3 and separated from copper.In dilute hydrochloric acid medium,the absorbance was measured by atomic absorption spectrometer with air-acetylene flame at 217.6 nm wavelength.The method has been used to the determination of trace antimony in electrolytic copper with RSD of 0.19%.This method is simple and rapid. |
