3.2. Elution profile
The elution of metals fromretained aminoacids onto solid substrates
in the presence of acids occurs fast with high recoveries. Column A was
loaded with 5 mL of a 10 μg Sb L−1 solution and Fig. 2 shows the timedependent
transient signal obtained when Sb(III) was removed using
15% HCl as eluent. The transient signals for a complete metal removal
