title: [Determination of indium in whole blood by graphite furnace atomic absorption spectrometry].
abstract: OBJECTIVE
  To investigate the sensitization effect of different chemical modifiers in the determination of indium in whole blood by graphite furnace atomic absorption spectrometry, and to develop a new method for the determination of indium in whole blood.
  
  
  METHODS
  A mixture of 0.3% HNO3 (V/V) + 0.1% Triton X-100 (V/V) was used as a diluent, and a solution of 1 000 µg/ml Pd (NO3)2 + 3 000 µg/ml Mg (NO3)2 was used as modifier. After being diluted five times, the concentration of indium of the blood was directly determined by graphite furnace atomic absorption spectrometry.
  
  
  RESULTS
  The detection limit of the method was 0.33 µg/L, the linear range was 0.33~100.00 µg/L, the relative standard deviation was 1.43%~2.65%, and the recovery rate was 98.3%~105.3%.
  
  
  CONCLUSIONS
  The method is simple and fast and has high recovery and precision, and it is suitable for the determination of indium in whole blood.
