便携式X射线荧光光谱仪快速鉴别硫熏八角
目的建立用便携式X射线荧光光谱仪快速筛查硫熏八角的方法。方法选定土壤模式测定干燥后新鲜八角含硫量,测定时间80 s,测得硫含量为905~1852 mg/kg。将干燥后新鲜八角含硫量作为参照值,对市售干八角是否硫熏进行快速筛查。同时,按农业部标准检验上述市售八角,并进行判定。结果 8批市售干八角中,7批含硫量远超出参照值,为硫熏八角。1批样品的含硫量在参照值内,为未硫熏的八角。该结果和农业部标准判定结果一致。结论便携式X射线荧光光谱仪能快速准确地筛选出硫熏八角。...

| Abstract_FL | Objective To establish a method of rapid screening of sulfur fumigated star anises by field-portable X-ray fluorescence (XRF).Methods The sulfur content of dried fresh star anises was detected by soil model.The test time was 80 s and the result of sulfur content was 905～1852 mg/kg.Setting the sulfur content of dried fresh star anises as the reference value,the dry star anises of market were quickly screened.The samples were also tested according to the method of the Ministry of Agriculture.Results The content sulfur of 7 batches were more than standard,which should be determined as sulfur fumigated star anises,and the other one sample was not fumigated,ofwhich the content was low than standard.The results of XRF were in accordance with the method of the Ministry of Agriculture.Conclusion The portable XRF can be used for rapid screening of sulfur fumigated star anises. |
