摘要
Abstract
[Objective]The aim was to establish a method by Inductively coupled plasma mass spectrometry for the determination of lead, cad-mium, mercury, arsenic, chromium and copper in Fucheng Ophiopogon japonicus, and study the heavy metal content of Fucheng Ophiopogon japonicus.[Method]After the sample was digested by microwave, the contents of lead, cadmium, mercury, arsenic, chromium and copper in Fucheng Ophiopogon japonicus were determined by ICP-MS.[ Result] The linear relationship of each element was good; r was greater than 0.9990; the RSD of precision test was less than 5%; the recovery rate was 91.8% -103.0%, and the detection limit was less than 0.01 mg/kg.[Conclusion]The method is simple and sensitive,so it can satisfy the determination demand for Fucheng Ophiopogon japonicas.关键词
