| Abstract: | A new and highly-sensitive method for determination of trace Os(Ⅷ) was developed on the basis of Os(Ⅷ) catalysted reaction of Luminol and O2 which generates chemiluminescence. The detection limit of this method is as low as 1.8×10-14 g/mL for Os(Ⅷ) and the relative standard deviation (RSD) for determination of 1.0×10-13 g/mL Os(Ⅷ)(n=13) is 4.2%. These is a linear relationship between chemiluminescence and Os(Ⅷ) concentration in the range of 3.3×10-13 g/mL to 1.3×10-9 g/mL. The method proved to be simple and effective for determination of trace osmium, with good reproduceability and high sensitivity. |
