| Abstract: | The samples were decomposed bynitric acid,potassium chlorate and sulfuric acid. The contentsof arsenic were determined by iodimetric method. The method was simple andaccurate. Recoveries were in the range of 98.20～101.60% and RSD`s were found to be less than 2.0%. The measurement range of this method was 0.2～3.0%. |
