Exploration of Microwave Digestion ICP-AES Technology for Determing Micro Heavy Metal Elements in Soil
This experiment analyzed and determined the content of heavy metal elements Cr,Zn,Mn,and Cu in soil samples using acid assisted microwave digestion and inductively coupled plasma atomic emission(ICP-AES)technology.The results showed that the contents of Cr,Mn,Cu,and Zn in the soil were 62.47 mg·kg-1,284.50 mg·kg-1,47.07 mg·kg-1,and 98.98 mg·kg-1,respectively,which did not exceed the soil pollution risk control value for agricultural land.The experiment shows that this method is used to analyze and determine the content of metal elements in complex samples,which has the advantages of simple operation,rapid analysis,high sensitivity,good accuracy,and low detection limit,and has broad application value.
