Complexation of Chromium, Aluminum, and Iron Ions with Monocarboxy Cellulose

Metal oxides and polysaccharides: an efficient hybrid association for materials chemistry

“…Fe(III)-cellulose, 107 Cu(II)-cellulose, 108 Zn(II)cellulose, 109 Pb(II) and Cd(II), 110 or Cr(III) and Al(III). 111 This could improve or introduce properties of the cellulose (mechanical, absorbent, anti-microbial and -fungal, UV self-cleaning, dissolution), but could also be detrimental to its stability. 112 These authors highlighted the important role of both the pH and the residual carboxylic group of the cellulose.…”

An Ultra-Low Detection Limit Fe3+ Optical Fiber Fluorescent Sensor Based on a Anti-B18h22 Derivative with Aggregation-Induced Emission Enhancement

“…13, the characteristic peak of the sensing film around 3000 cm -1 is ascribed to the stretching vibration of O-H, which almost disappeard after combining Fe 3+ . The appearance of new peak located at 1090 cm-1 is related to the O-Fe bond [39,40] . In addition, affected by the movement of the electron cloud caused by the addition of Fe 3+ ， the intensity of the absorption peak at 1740 cm-1 ascribing to the stretching of C=O bond decreased greatly.…”
