| Abstract: | Objective:A method to determine boron in food was established by ICP-OES.Methods: The samples were digested by HNO3 in high-pressure closed-vessel,then the solution was analyzed by ICP-OES to determine the content of boron.Results: The calibration curve showed good linearity in the range of 0 mg/L~10 mg/L with linear coefficient of 0.99999,the detection limit was 0.44 mg/kg,relative standard deviation was below 4.0%,the result of analyzing standard material was in the range of certificate value.Conclusion: The method showed wide linear range,good precision and accuracy,it was suitable for determination of boron in food. |
