| Abstract: | The sludge samples at five arsinic levels were determined in six labs, in order to decidethe precision of the hydride generation-atomic absorption spectroscopy (HG-AAS)of determining thearsinic content of sludge from the petroleum refining industry. The experimental results show that therepeatability of HG-AAS can be exprressed by lg r= -0.678-0.764lg m and the reproducibility byle R = - 0.448 -0.845 lg m. |
