N -methylene phosphonic (NMPC) chitosan was studied by several techniques to determine their properties in aqueous solution and its capacity to emulsify edible oils. The phosphonic groups are all equivalent and their ionization constants were estimated (p K a1 =6.45 and p K a2 =11.75). The ...

Hence, the metal sorption increased on the sorbent surface. For cross-linked magnetic chitosan (CMCT) (as a control) the sorption is still at a modest level (from 0.216 to 0.228 mmol U/g) over a wide range of pH0: 4.0 to 5.5 (pHeq: 4.80 to 5.42), showing that Cys has a higher ...
