Determination of surface sulfate groups of cellulose nanowhiskers obtained by various desulfation procedures: usefulness of different methods for sulfate group quantification

Synthesis and structural design of microspheres comprising cellulose nanofibers and artificial lignin polymer by enzyme-mediated Pickering emulsion templating

“…† An explanation for this is that surface modication by the introduction of carboxy, sulfate, or phosphate groups promoted electrostatic adsorption, whereas only physical adsorption may have occurred on the native CNF. 39,40 We investigated the desorption behavior of the ALP/CNF microparticles at pH 2.5 (Fig. 6a) and pH 7.0 (Fig.…”
