This article considers the modification of cellulose fibres with the use of vinyltrimethoxysilane and maleic anhydride as substances to improve the wettability of the additive in the hydrophobic polymer matrix. The stress is put on the possible ways of modification impact investigation and its description. Effects of the treatment are analysed using Fourier transform infrared spectroscopy, which reveal the presence of new moieties on the cellulose surface, e.g. C=C bonds, C=O and Si-C groups, while dynamic light scattering investigation revealed an increase in the hydrodynamic radii of the molecules which was maximized in the case of modification with the use of maleic anhydride. Furthermore, thermal properties were defined with differential scanning calorimetry and thermogravimetric analysis. Some variations within the process of samples thermal degradation are observed-thermal stability of the specimen modified with maleic anhydride is the highest. The presented approach of combined fibre modification analysis techniques, being a scientific novelty, allows to confirm the treatment impact on cellulose properties at many levels.

“…It is usually synthesised by a two-step alkali-catalyzed reaction of cellulose with monochloroacetic acid (MCA). First cellulose is converted to alkali cellulose in the presence of sodium hydroxide and then the alkali cellulose is reacted with mono chloroacetic acid to form CMC sodium salt (Joshi et al, 2015;Nevell & Zeronian, 1987).

“…Many researchers reported the synthesis of CMC from cellulosic materials including sugar beet (Togrul & Arslan, 2003), banana pseudo stem (Adinugraha, Djagal W., & Haryadi;, flax short fibers (Kutsenko, Bochek, Vlasova, & Volchek, 2005), sago waste (Pushpamalar, Langford, Ahmad, & Lim, 2006), paper sludge (He, Wu, Fua, & Nia, 2009), cotton stalk (GenLin; Zhang, Zhang, Deng, & Sun, 2011), corn (Kumar Singh & Kumar Singh, 2012, bamboo shaving (Chen & Lou, 2014), water hyacinth (Saputra, Qadhayna, & Pitaloka, 2014), office waste paper (Joshi et al, 2015) and corn husk (Mondal, Yeasmin, & Rahman, 2015). Conventional synthesis of CMC is time consuming reaction.…”

“…CMC is widely used in oil exploration, detergents, cosmetics, paper products, food and textile industries. Synthetic CMC obtained directly from market offers 0.51 degree of substitution (DS), and laboratory-made CMC from bagasse has a DS of 0.65 (Gulati et al 2014;Joshi et al 2015;Mohkami and Talaeipour 2011). This higher DS of laboratory-made CMC results in better use in the commercial products (Yeasmin and Mondal 2015).…”

In this study, bio-polymeric gel beads were made from synthetic and laboratory-made CMC (bagasse). Calcium chloride cross-linked with sodium alginate (Na-Alg) added to CMC displayed great affinity for the removal of hexavalent chromium (Cr(VI)) ions present in an aqueous solution. Activated carbon obtained from bagasse was also used for adsorptive removal of Cr(VI) ions from aqueous solution. The effect of different adsorption parameters such as pH, contact time and adsorbent dosage was studied. Bio-polymeric gel beads and activated carbon were prepared and characterized by SEM, FTIR and XRD. The maximum percentage removal for synthetic and bagasse bio-polymeric gel beads reaches 94.56% and 98.42% values at a pH of 4.0 at 25 °C and for activated carbon 64.79% value at a pH of 6.0 at 25 °C. Higher degree of substitution results in an increase in the percentage removal of Cr(VI) ions due to the increase in the surface area and the binding sites of the adsorbent. Our study suggests that bio-polymeric gel beads made from laboratory-made CMC (bagasse) can be used in a more cost-effective and efficient way for the removal of harmful chromium ions.
