“…It is also apparent that Ca 2+ has a much higher affinity than Na + , resulting in a significant lower of Na + sorption when pH increased. These competitive characteristics have been previously observed [16].…”

“…This result postulates that the total charge, which is determined by the potentiometric titration using sodium hydroxide, is not always a reliable method applied to cations that can form complexes. The total charge of the pulp was 186.6 meq/kg which was determined using the potentiometric method [17]. If a divalent Fe 2+ ion binds with two negative sites on the fibre, the sorption capacity of the fibre will be 93.3 mmol/kg of Fe 2+ .…”

“…The pronounced influence of pH and ionic strength of solution to the distribution of metal ions on the distribution coefficient have been also reported [5,[9][10][11][12][13][14][15][16]. The kinetics and isotherm sorption of Na + and Ca 2+ onto unbleached kraft fibres was previously studied in details by Duong et al [17].…”
