Therefore, special care must be taken regarding the reagents used and their concentrations if total element extraction is the desired result. 5 US-SLE Extraction from Plants The elements Ca, Mg, Mn, Zn, Co, Ni, Cu, Ba, Fe, Pb and Cd have been extracted from plants using either an UB or an UP with different degrees of success [30–36]. As a general trend, Ca, Mn, Mg and Cu are totally extracted. Fe, Cr, Zn and Ni are highly extractable, with recoveries ranging from 70 to 100%. Barium is extracted in low percentages .
Since it was reported to the scientiﬁc community in 2004, ultrasonic assisted enzymatic digestion (USAED) using an UP has become a routine method for element speciation [11, 12, 39]. Nevertheless, the methodology is still being developed. Although enzymes were previously described in the literature as a tool for chemical speciation, as explained above, never before had the enzymatic reaction kinetics been speeded up using an UP for element speciation purposes. Previously, the enzymatic hydrolysis was accelerated by means of UBs or heating baths at 37 C.
2 Mass of Matrix One of the advantages of ultrasonication is that it can be performed in such a way that minimum amounts of sample are needed, providing that the ﬁnal element concentration lies in the linear range of the detection method [16, 17]. For a given volume, for instance 1 mL, 10–100 mg can be used, when ensuring that longer sonication times are used for higher amounts of sample. Importantly, for a constant volume, the higher the mass of the matrix used, the higher the concentration of substances co-extracted, for instance organic matter.
