摘　　要：试样用王水溶解 ,加入少许氟化铵 ,蒸至近干后 ,加入HBr +HClO4 混酸 ,冒烟至尽 ,去除对测定铟有严重干扰的锑、锡、硅、硫酸根等离子。在硝酸介质中 ,于波长 3 0 3 9nm处 ,在火焰原子吸收光谱仪上 ,测定铟的吸光度。此法快速、简便、准确 。The samples were dissolved in hydrochloric acid and nitric acid (1:3),to which a few ammonium fluoride have been added and then in order to eliminate the interference of antimony,tin,silicon,sulfate with the determination of indium,a certain amount of hydrobromic acid was added,then evaporated and fumed till to be exhausted Indium was determined in the medium of nitric acid by flame atomic absorption spectrometry at 303 9nm The method is rapid,simple and precise
