The flotation separation behavior of apatite from calcite using carboxymethyl chitosan as depressant

Investigation on preparation of carboxymethyl chitosan modified sodium ferric silicate and its adsorption properties

“…[36,37] This is consistent with the molecule. [38] This also shows that CC has been successfully adsorbed on the surface of SFS. The O 1s spectra of could be fitted to two peaks at 531.86 and 529.56 eV, corresponding to adsorbed hydroxyl groups (OH À ) and lattice oxygen anion ions (O 2À ), respectively.…”

“…2b), the asymmetric stretching in the vibration band of the C-O group appeared at 1422 cm À1 , and the peaks around 873 cm À1 and 713 cm À1 correspond to deformation in the vibration bands of the C-O group in calcite. 19,20 The bands at 567 cm À1 and 606 cm À1 correspond to the n4 bending modes of PO 4 3À . 21 In addition, the band at approximately 1035 cm À1 corresponded to the n3 bending mode of PO 4 3À .…”

“…26 The vibrational bands of amide (NH-CO) and alkoxyl (C−O) can be obviously observed in SD-Si/CMCS and pure CMCS, which are weakly covered by the broad and strong stretching vibration peak of Si−O−Si at ∼1095 cm −1 in M-Si/CMCS. 36 Moreover, the peak of Si−O−Si asymmetric stretching around 1000−1200 cm −1 in pristine Si is broadened and blunted in SD-Si and SD-Si/CMCS, providing evidence of SiO 2 and more active sites on the Si surface. 37,38 This analysis is further confirmed by the Si 2p in XPS spectra (Figure S5).…”
