【Abstract】 This paper is about the effect of trivalent chromium a nd hexavalent chrome in the determination of the flame atomic absorption spectro photometry.The tests showed that the different flame and the state of the flame, the height of the burner,coexistent metal,acid medium,and the existence of sodiu m dodecyl sulfate and kalium could cause the different effect of the absorbency.更多还原
