3 PRINCIPLE OF THE METHOD

The sample to be tested is placed in a muffle furnace at 700 ℃ calcined at 10h, the resulting molten ash using a mixture of boric acid and sodium carbonate, with Dilute hydrochloric acid to dissolve the melt, the resulting solution Determination of trace elements using atomic absorption spectrometry.

4 Reagents

4.1 anhydrous sodium carbonate (excellent pure). 4.2 borate (excellent pure).
