| Abstract: | The acidity conditions are discussed about determination of calcium with AAS （flame atomic absorption spectrophotometry）. The optimal acidity condition on determination of total chromium was given by testing calcium in different acidity condition of hydrochloric acid and nitric acid. The some advices were listed. The sensitivity of the method for determination of calcium is observably enhanced with the advices. |
