| Abstract: | After dissolved by nitric acid, several same samples were added into the five element standard solutions increased by concentration degrees,respectively,then the contents of copper,calcium,iron, manganese and nickel were determined succes - sively by air - acetylene fire atomic absorption spectrome-try(FAAS) .The optimum determination conditions have been established. The interference tests for other ele ments that probably esist have been conducted.The rate of recovery is 98.4% - 102.5% ,the relative standard deviation is 1.9% -3.0%. |
