High-grade cellulose (97% α-cellulose content) of 48% crystallinity index was extracted from the renewable marine biomass waste Posidonia oceanica using H2O2 and organic peracids following an environmentally friendly and chlorine-free process. This cellulose appeared as a new high-grade cellulose of waste origin quite similar to the high-grade cellulose extracted from more noble starting materials like wood and cotton linters. The benefits of α-cellulose recovery from P. oceanica were enhanced by its transformation into cellulose acetate CA and cellulose derivative GMA-C. Fully acetylated CA was prepared by conventional acetylation method and easily transformed into a transparent film. GMA-C with a molar substitution (MS) of 0.72 was produced by quenching Fenton’s reagent (H2O2/FeSO4) generated cellulose radicals with GMA. GMA grafting endowed high-grade cellulose from Posidonia with adsorption capability. GMA-C removes β-naphthol from water with an efficiency of 47%, as measured by UV-Vis spectroscopy. After hydrolysis of the glycidyl group to glycerol group, the modified GMA-C was able to remove p-nitrophenol from water with an efficiency of 92%, as measured by UV-Vis spectroscopy. α-cellulose and GMA-Cs from Posidonia waste can be considered as new materials of potential industrial and environmental interest.

“…Compared with the other adsorbents reported in the literature such as AP-55 (280 mg/g), granular activated carbon (32.9 mg/g), charcoal activated powder (187.1 mg/g) (Daifullah and Girgis 1998), activated carbon fibers (418.3 mg/g) , carbon nanospheres (32.8 mg/g) (Lazo-Cannata et al 2011), yellow bentonite (9.9 mg/g) (Yaneva and Koumanova 2006), MIP-SiO 2 (15.6 mg/g) (Luo et al 2008), olive wood (5.9 mg/g) (El-Sheikh et al 2013) and cotton cellulose C2 (11.2 mg/g) (Vismara et al 2009), it can be concluded that the two adsorbents can be used to remove 2,4-DNP from aqueous solutions as effectively as the other adsorbents. Further compared with the previously synthesized imidazole-modified silica adsorbents in our group such as SilprImCl (33.3 mg/g), SilprM 1 ImCl (33.9 mg/g), SilprM 2 ImCl (35.9 mg/g), SilprM 4 ImCl (37 mg/g) and SilprM 1 M 2 ImCl (35.3 mg/g) (Wang et al 2013a, b), it is apparent that SilprP 3 NImBr and SilprSP 3 NImBr show adsorption ability superior to the other imidazole-modified silica adsorbents reported in the literature and is more effective for the adsorption of 2,4-DNP, which may be attributed to the additional electrostatic interactions between the amino groups and 2,4-DNP molecules.…”

Amino group exhibits alkaline properties. Amino functionalized imidazole-modified silicas would benefit the adsorption of phenolic compounds. Coupling agent between the silica and the imidazolium ring has an effect on adsorption performance. In this paper, two adsorbents were synthesized for the surface bonding of N-(3-aminopropyl)-imidazole onto silicas modified by 3-chloropropyltriethoxysilane and 3-mercaptopropyltrimethoxysilane, respectively. Infrared spectra, elemental analysis, thermogravimetric analysis and N 2 adsorptiondesorption isotherms were used to characterize the two adsorbents, and their adsorption capacities of 2,4-dinitrophenol from aqueous solutions were investigated in detail. The experimental results indicated that amino group plays an important role in the enhancement of adsorption capacities of 2,4-dinitrophenol. The adsorbent with 3-mercaptopropyltrimethoxysilane as coupling agent exhibited lower adsorption capacity due to a weak electron-electron repulsion between the non-bonding electrons of sulfur atom and p electrons of benzene ring of 2,4-dinitrophenol. The adsorption kinetics fitted well with pseudo-second-order model. The two adsorbents could be regenerated and reused eight times at least by washing with HCl. The adsorption mechanism was also discussed.

“…Cotton fabrics grafted with GMA or GMA/␤-CD were reacted with ␤-CD. The fabrics were placed in a solution containing 2% ␤-CD, 1 M NaCL, and 1% NaOH (Vismara, Melone, Gasalldi, Cosentino, & Torri, 2009) The solution was stirred at 80 • C for the desired time. The grafted fabric was washed with distillated water, then dried and weighed.…”
