| Abstract: | Samples were pulverized,sieved and made into agar suspension,the solution was diluted with suitable amount of agar solution,injected into air-acetylene flame for determination by FAAS.Compared with those of ashing method,there is no difference was found between the two methods.The suspension sampling method is convenient,rapid and accurate. |
