| Abstract: | Milk powder is solvated in 1.0% hydrochloric acid,instead of being digested,and injected into air-acetylene flame by standard series method to determine calcium.The results are consistent with those obtained by normal digesting method.The recovery is 97.2%～102.8%and the relative standard deviation is less than 2.1%. |
