| Abstract: | Inductively coupled plasma atomic＇, emission spectromeu7 （ICP-AES） was used to determine borax content by microwave digestion sample. Results showed that it was a method with a good linear relationship and R2= 0.9991. Detection limit was 0.46mg/kg. Recovery rate was 91.7%-105.0% with three gradient concemrations. That was a summay, high precision and good accuracy method, and could meet requirement for boron determination. |
