| Abstract: | Atomic absorption spectrophotometry was used to determine trace lead in quinoa. Five different methods of pretreatment were studied.Effect of determination of lead content in wheat. The recoveries of the five methods were 95.4%~104.8%. The results of the analysis of reference materials were consistent with the recommended values. The microwave digestion method had the advantages of simple operation, complete resolution, high stability, and low pollution. The determination of lead content has great application prospects |
