Determination of micronutrient by inductively coupled plasma atomic emission spectroscopy in solid biomass fuel
A comparative analysis was conducted on the pre-treatment methods of trace element samples in solid biomass fuels,and the micro wave digestion program was determined.The detection limit of the method for determining trace elements by inductively coupled plasma atomic emission spectrometry was given.The linear equation correlation coefficient of each trace element was 0.999,and the average recovery rate was between 87.72％and 109.49％.The accuracy and repeatability of the method were verified using standard reference materials,and the measured values of each element were within the range of the standard certificate values,with a relative standard deviation of 0.59％to 6.25％.The precision of the method was determined through collaborative experiments conducted by 7 laboratories.F-test and t-test indicate that there is no significant difference between inductively coupled plasma a-tomic emission spectroscopy and flame atomic absorption spectroscopy.
