Abstract:
Objective To analyze and discuss the content determination of As and Hg from Lilium Lancifolium in Longshan County; To optimize microwave digestion conditions. Methods Automatic microwave digestion appratus was used. Lilium Lancifolium samples from Longshan County were digested in teflon microwave tube with HNO3-H2O2, and As and Hg were measured with atomic fluorescence spectrometry (AFS). Results The content of As was in the range of 0.031–0.507 mg/kg, and the highest content of Hg was 0.024 mg/kg. The regression equation was Y=221.23X+170.72(r=0.995 9),Y=503.52X-682.43,(r=0.999 2).For the production base,the recoveries of As and Hg were 94.32% and 92.48% in the samples, and RSD were 2.14% and 2.70%; for the breeding base, the recoveries of As and Hg were 94.95% and 93.52% in the samples, and RSD were 1.15% and 1.97%. Conclusion The method is simple and reliable, which can be used to the content determination of As and Hg from Lilium Lancifolium, and provide references for the choice of base of production and breeding of Lilium Lancifolium in Longshan County.
