Mobilite et extraction des metaux lourds associes aux boues de …
The mobility and extraction of nickel and cadmium were investigated by the action of acids [sulphuric (Table 6) and acetic (Table 7)] and saline solutions [calcium chloride (Table 8), and ammonium acetate (Table 9)]. Nickel is easier to extract from the sludges than cadmium, and acetic acid is the reagent that gives the best extraction yields.
