| Abstract: | With HCl,HNO3,HF and HClO4 dissolved samples,indium content in the last placer was determined by the use of flame atomic absorption spectrophotometric,of which the working conditions,instrument choice and reaction conditions were optimized.The experimental results show the linear range of 0～10μg·ml-1,the linear equation of y=0.001809+0.01497x,the correlation coefficient of 0.9994,the detection limit at 0.090μg·ml-1,RSD of 1.39%,96.0% and recovery rate of 106.0%.This method is simple,accurate and precise,and can meet the analysis requirements. |
