【Abstract】 Flame atomic absorption spectroscopy direct determination of total chromium was studied in this paper. The optimal analytical conditions was ascertained through different condition experiments,analytical precision and accuracy were also validated by means of analysis of standard samples and realistic samples. Based on a lot of experiments ,the quality control map of blank test and accuracy were set up to regularly provide effective measures of quality control for all sorts of monitoring data. The experimental results showed that this method was easy to operate,analytical efficiency was promoted,analytical precision and accuracy were good as well ,so we think this method could be applied and popularized更多还原
