Temperature: |
298.0 K |
pH Range: |
4.5-9 |
Ligand Concentration Range: |
1E-13 - 1E-14 mol/L |
Fit Method: |
EQIL-DISSOL |
Comment: |
log K = -3.41 for I = 0.01 M; solid concentration 10 and 50 g/L; no influence of ionic strength, presence of small amounts of carbonate (<1E-4 M) induces no change in sorption |
