摘    要:本方法采用氢化物发生原子荧光光谱法测定钨精矿中锑量。经实验确定了测定锑量的最佳分析条件:试样经硫酸-硫酸铵分解,用柠檬酸在氨性介质中络合钨、铁、锰等,用抗坏血酸预还原五价的锑到三价,样品溶液在15%的酸度中,经流动注射-氢化物发生器与原子吸收分光光度计联用测定锑量。该方法具灵敏度高,准确性好,快速简便,干扰元素少等优点。检出下限可到0.001%锑量。

关 键 词:氢化物发生  钨精矿

Abstract:The Sb amount in tungsten concentrate is determined by hydride generation atomic fluorescence spectrometry.The optimal analysis conditions is obtained by means of experiments:the sample is decomposed by sulfuric acid-ammonium sulfate,coordinated with tungsten,iron,manganese in ammonia medium using citric acid,then reduced pentavalent Sb to trivalent Sb by ascorbic acid.Sb amount in the 15 % acid solution is measured by the united equipments:flow injection-hydride generator-atomic absorption spectrophotomete...
Keywords:hydride generation atomic fluorescence spectrometry  tungsten concentrate  Sb
