Note:
Measurements were performed in deionized water and in buffer mixtures; temperature for all measurements T
± σ = 20
± 3°C.
Standard deviations are errors from linear regressions performed. AC lot
= two lots obtained from the supplier Donau Carbon were
used (old lot 1 kg; (April 2006), new lot 20 kg (July 2008); Analytics
= analytical method used; K
(unit mg 1−n
g −1
L n
) and n
(without a unit)
are the Freundlich parameters with standard deviations; r 2
= goodness of fi t of the linear regression from log (q) versus log (c);
N
= number of data points; and c
0 = start concentration in mg/L.
