Determination of Heavy Metals in Particulate Matter by Inductively Coupled Plasma Mass Spectrometry(ICP-MS)
During the whole process of monitoring heavy metals in particulate matter,sampling,control of reagent blank and filter(cartridge)Blank,pretreatment,and laboratory analysis may affect the accuracy of analysis,especially,in the digestion process,the digestion efficiency of different metal elements by different digestion methods is the key factor affecting the accuracy of monitoring results.Microwave digestion and electrothermal plate digestion of the same samples were Inductively coupled plasma by ICP-MS,the effects of different digestion methods on detection limit,blank of filter,accuracy and precision were analyzed and compared,so as to provide reference for the optimization of digestion methods of heavy metals in particulate matter.
