Getting organic chromium by cultivating chromium-enriched mungbean sprouts was studied. Chromium content in mung-bean sprouts was determined and the growth performance was observed under different conditions. The result showed that the optimal condition of cultivating chromium-enriched mungbean sprouts was soaking mungbean seeds in 40 mg/kg chromium solution about 24 hours, then cultivating under 25 degrees C for 5 days. The supernatant of chromium-enriched mungbean sprouts and normal mungbean sprouts were tested by scanning with ultraviolet spectrometry within the range of 200-320 nm wavelength. It is found that a characteristic ultraviolet absorption peak appears at 257 nm, and its optical density is descended with the increasing of chromium in the chromium-enriched mung-bean sprouts.
