Abstract

The contents of selected toxic trace metals (Cu, Pb, Cd and Cr) and macronutrients (Na, Mg and Ca) in Suaeda glauca Bge, were extracted by four approaches containing conventional immersion approach, ultrasonic-assisted extraction, microwave-assisted extraction and acid digestion approach, then analyzed by flame atomic absorption spectrophotometer (FAAS). The comparison of the results showed that the metal contents released were approximately equal in former three approaches, but lower than those of acid digestion approach that extracted entire metals from Suaeda glauca Bge leaf and seed. The contents of metals from the leaf and seed of S. glauca were found at different levels, and showed a similar trend in the following order: Na > Cu > Ca > Mg > Cd > Pb > Cr, but the values of metal in leaf showed higher than those of seed except Na and Ca.. Meanwhile Suaeda glauca Bge was found to be a good hypertolerant plant for Cu.
