HPLC-ICP-MS法测定香菇及培养料中不同形态砷的含量
Species analysis of arsenic in Lentinus edodes and culture medium by HPLC-ICP-MS
摘要
Abstract
The method for determination of arsenite (As (Ⅲ)),arsenate (As (V)),methylarsonic acid (MMA),dimethylarsinic acid(DMA),and arsenic betaine (AsB)arsenic species in Lentinus edodes and culture medium by HPLC-ICP-MS has been developed.Samples were extracted with ultrasonic instrument in 70 ℃,then separated by HPLC on an anion chromatography and quantification by ICP-MS.Good linearities of 5 arsenic species were observed with correlation coefficients above 0.9999,the linear range was 0～100.0 ng/mL.Recoveries were between 81.0％ and 108.9％ and the relative standard deviation were within 1.6％～6.3％ (n =6).With the actual samples tested the As(V) was the main species in culture medium.The content had little relation with its cultivation time.It had more content As (Ⅲ),As (V)and AsB in Lentinus edodes.Although the total arsenic results conform to the requirements of the national standards,but high toxic inorganic arsenic are majority.关键词
