中文摘要:
      采用王水溶解样品,5%(V/V)王水介质中,以Au 242.795 nm作为分析线,建立了电感耦合等离子体原子发射光谱(ICP-AES)法测定硒碲渣中金元素含量的方法。选择仪器的最佳工作条件为射频功率1 150 W,雾化器流速0.8 L/min,观测高度10 mm。校准曲线的线性相关系数在0.999 8以上,结果的相对标准偏差小于3%。方法的加标回收率在98.4%~103%。方法快速,简捷,测定结果与火试金-原子吸收光谱法结果相吻合。
英文摘要:
      Sampleswere dissolved by aquaregia and the content of gold in selenium tellurium slag was determined in 5%(V/V)aquaregia medium by inductively coupled plasmaatomic emission spectrometry (ICP-AES) using Au 242.795nm as analytical line.The optimum operating conditions for selecting the instrument were: 1 150 W RF power,0.8 L/min atomizer fiow rate, and 10 mm for theobservation height. Calibration curves had linear correlation coefficients above 0.9998, andrelative standard deviationsless than 3%.The spiked recoveries were in the range 98.4%—103%.The proposed method is rapid and simple, withresults arein agreement with flame atomic absorption spectrometry.
