| Abstract: | Objective To investigate the fast detection method of chromium in the gelatin hollow capsules. Methods The microwave two steps digestion- graphite furnace atomic absorption spectrometry was adopted to rapidly determine the chromium content in the cap- sules. Results This method had a good linear relation with r =0. 999 4. The detection limit was 0. 47 ng/mL. The average recovery rate was 97.6%. Conclusion This method is fast, sensitive and accurate with good reproducibility and provids the rapid detection method of the chromium content in the capsules. |
