“…Furthermore, another band at 1518 cm −1 could be ascribed to the bending vibration of the N-H bond. 31 It is worth noting that the stretching vibration bands of P=O and O-P-O bonds were covered by the asymmetric stretching vibration bands of the C-O-C, bridge which caused a broad absorption band at 1153-1004 cm −1 .…”

Herein we synthesized Cu(II) immobilized on Fe 3 O 4 @Agarose functionalized with ethanolamine phosphatesalicylaldehyde Schiff base (Fe 3 O 4 @Agarose/SAEPH 2 /Cu(II)) as a new and cost-effective nanomagnetic catalyst. The nanomagnetic catalyst was characterized by FT-IR, XRD, VSM, SEM-EDX, TEM, TGA, and ICP techniques and it was found that the particles were about 9-25 nm in size and spherical with entrapment of the Fe 3 O 4 particles in the hollow pore structure of the agarose. The prepared nanomagnetic catalyst showed excellent activity for preparation of 2-substituted imidazolines, oxazolines, and thiazolines. The catalyst is easy to prepare and exhibits higher catalytic activity than some commercially available copper sources. More importantly, this nanomagnetic catalyst can be easily recovered by using a permanent magnet and reused for at least seven cycles without significant deactivation.

“…12 The bonding between them involves electrons donation by Lewis basic atoms such as N, O, P, S, from the sorbent to the metal ions as Lewis acids. 13 In general, the accessibility to these donating centers species to a great extent the selectivity of a sorbent to specic metal ions.…”

“…Therefore, the need for low cost solid adsorbents based on natural or synthetic polymers is ever growing. Our group has concentrated in developing synthetic polymeric adsorbents, modification of commercial polymers as adsorbent for various heavy metal ion adsorption from aqueous solution [7][8][9][10][11] . However, synthesis of these polymeric adsorbents is costlier and the disposal of spent adsorbent may cause environmental problems.…”

A novel chemically modified cellulose (Cell-DMA) adsorbent using Schiff base tertiary amine-chelating group was synthesized for the removal of Hg 2+ metal ions from aqueous solution. Mercury is a highly toxic, environmental pollutant, which requires new ecofriendly green adsorbent material for its removal from wastewater. The physical and chemical characteristics of the adsorbent (Cell-DMA) were determined by FTIR, 13 C NMR, SEM and EDAX analysis. The well-characterized chemically modified cellulose (Cell-DMA) was used for the removal of mercury (II) ions from aqueous solution using batch adsorption process. The obtained data were analyzed with various kinetic and isotherm models and it was found that the pseudo second order kinetic model and the Langmuir isotherm were well suited for the adsorption of mercury (II) ions from aqueous media.
