3.2.2. Pretreatment temperature
In the 10% HF seawater medium, pretreatment curves of
Cu are similar, with or without the use of palladium. For
Mn, the remaining fluoride interference effect is suppressedby using a pretreatment step at about 1300 ◦C. For Cu and
Mn, a pretreatment step at about 1300 ◦C permits to eliminate
sodium salts. In these conditions, due to the absence of Mg
and Ca species, atomization of Cu and Mn can be performed
in total absence of absorbing matrix (i.e., ˜ABG = 0) when Pd
is not used.
