The interaction of CTAB with CNCs, and potential alterations on the chemical and physical structure of CNCs are studied, and the synthesized adsorbent, modified cellulose nanocrystal (MCNC) was characterized using Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, elemental and zeta potential analysis. 详细>
