| Comment: |
uncertainty represents 95% confidence limit, experimental data from [YH75], [BM81), (HL85), [HREL91], (M92], SSD from [DM90]; SSA from [T93b]; ionic strength ranging from 0.0004 to 1 M, data were corrected for ionic strength effects; pK-values fixed by convention: (pK1+pK2)/2 = pH(PZC) and delta(pK) = 4 [HREL90] |
