【Abstract】 A method for determination of As in soils by water bath -- Atomic Fluorescence Spectrometry was studied. Contrasting with the traditional mixed acid digesting, this method not only shortened the time of fore-treatment process, but reduced the reagent cost. The experiment error, which was caused by factors such as sample solution splashing during the process of wet digestion, was also avoided. The method was simple, rapid, accurate, sensitive. the results obtained by the method were satisfactory.更多还原
