Inductively coupled plasma mass spectrometry (ICP/ MS) was used to measure the content of major inorganic elements (Na, Mg, P, K, Ca, Mn, Fe, Cu, Zn, Cd, and Pb) in biomass samples. A representative sample (200 mg) of biomass was dissolved in 10 ml 65% nitric acid and 1.5 ml H2O2 based on US-EPA Methods 3051 and 3052. The vessel was sealed and heated in the microwave unit at 140 °C for 10 min, then 180 °C for 30 min (maximum power 1000 W). After they are cooled, the digested samples are analyzed by ICP/ MS.
