“…However, no considerable increase in % adsorption of Cd +2 and NB on increasing the adsorbent dose (0.96–1.2 g/L) was observed probably due to saturation of available sites. Similar trend has been observed by other workers for adsorption of Cd +2 or NB onto chitosan–cellulose, fluor‐hydroxyapatite composites, cashew nut shell resin (CNSR) functionalized Fe 3 O 4 magnetic nanoparticles, and nanostructured carbon…”

Molybdenum trioxide/polypyrrole (MoO3/Ppy) nanocomposite was prepared via oxidative polymerization of pyrrole monomer with MoO3 nanoparticles. The adsorption of Cd+2 and nile blue (NB) onto the nanocomposite was investigated in terms of various process parameters. The characterization of MoO3/Ppy nanocomposite was carried out by Fourier transform‐infrared spectroscopy, X‐ray diffraction, scanning electron microscopy, transmission electron microscopy, and energy dispersive X‐ray spectroscopy. Higher R2 (0.992–0.997 for Cd+2 and 0.997–0.998 for NB) and lower standard error of estimation values (1.04–1.82 for Cd+2 and 0.87–1.07 for NB) for Freundlich isotherm highlighted the multilayer adsorption onto heterogeneous nanocomposite surface. The higher Qm values at 323 K for Cd+2 (181 mg/g) and NB (189 mg/g) compared to many reported adsorbents proved the adsorptive superiority of MoO3/Ppy. The energy of adsorption (E) values from Dubinin–Radushkevich model was 1.26–1.38 and 1.36–1.44 kJ/mol for Cd+2 and NB, respectively, suggesting physical adsorption. Pseudo‐second order kinetic model governed the adsorption of Cd+2 and NB with intraparticle and liquid film diffusion controlling the mechanism. The negative ΔG values (8.4–9.4 kJ/mol) and positive ΔH values (2.5–6.1 kJ/mol) implied spontaneous and endothermic adsorption process. The positive ΔS values (0.036–0.048 kJ/mol/K) indicated increased randomness at MoO3/Ppy‐Cd+2 or NB interface. The MoO3/Ppy nanocomposite proved to be suitable and efficient adsorbent for sequestering of Cd+2 and NB from aqueous solution.

“…Moreover, there is growing research interest in the use of cellulose nanomaterials such as nanofibrillated cellulose and cellulose nanocrystals as eco-friendly fillers and reinforcement for existing composites (Moon et al 2011;Ä mmälä et al 2013). So far nanocellulose is produced from both forest and agriculture resources (Alemdar and Sain 2008;Chen et al 2011;Liu et al 2012, Rambabu et al 2016Rahmi and Julinawati 2017). Recently, the possibility of the use of fruit and vegetable pomaces as the source of cellulose was presented (Szymańska-Chargot et al 2017).…”

“…Cellulose nanostructures are usually used as a reinforcing agent for several polymers, but they can also be used as matrices for various materials, including films for food-packaging materials (Azeredoa et al 2017). Rahmi and Julinawati (2017) showed that hydrogen bonds forming between cellulose and chitosan helps to obtain good adhesion between both materials even without using surface modificators or coupling agents (Rahmi and Julinawati 2017). Most of the publication reporting results of chitosan reinforced by cellulose focused on commercial cellulose which unfortunately results in high-cost material (Abo-Elseoud et al 2018;Hassan et al 2011Hassan et al , 2016Trana et al 2013).…”

“…Nanocellulose, with its biocompatibility, biodegradability and good optical transparency, is the potential reinforcing agent for chitosan films (Fernandes et al 2010). Thus far, nanocellulose, both in the form of nanofibres or nanowhiskers, was used as the reinforcement of chitosan films (Fernandes et al 2010;Falamarzpour et al 2017;Dehnad et al 2014) and most of the studies are focused on the characterization of their mechanical and antibacterial properties (Li et al 2009;Rahmi and Julinawati 2017;Niu et al 2018;Toivonen et al 2015;Wu et al 2014). Moreover, the addition of nanocellulose could increase the flexibility and thermal stability of chitosan-nanocellulose films compared with native chitosan films (Fernandes et al 2010).…”

Influence of chitosan addition on the mechanical and antibacterial properties of carrot cellulose nanofibre film

et al. 2019

View full text Add to dashboard Cite

Films of carrot cellulose nanofibrils (CCNFs) with the addition of low-viscosity chitosan (CHIT) were prepared by the vacuum filtration. The chitosan content in the films varied from 9 to 33% (dry wt. basis). The surface morphology of the films was investigated by scanning electron microscopy, and it was found that chitosan was dispersed in the CCNF matrix. The interaction between CCNFs and CHIT was evaluated in terms of Fourier transform infrared spectroscopy (FTIR). The obtained results suggested physical interactions rather than hydrogen bonding between CCNFs and CHIT. This finding also supports the results of the water wettability experiment. The addition of chitosan to the nanocellulose matrix causes an increase in the water contact angle, i.e., the surface of the composites becomes more hydrophobic. This increase is probably connected to an interaction between nanocellulose and chitosan forming a denser structure. Analyses of thermal properties showed that the composites are stable under high temperature, and the degradation occurred above 300°C. It was found that the addition of CHIT to CCNF matrices caused a decrease in the Young's modulus-the higher that the concentration of chitosan in the composite was, the lower the Young's modulus (decreased from 14.71 GPa for CCNFs to 8.76 GPa for CCNF/ CHIT_5). Additionally, the tensile strength of composites, i.e., the maximum force that causes a fracture decreased after the addition of chitosan (decreased from 145.83 MPa for CCNFs to 129.43 MPa for CCNF/CHIT_5). The results indicated the highest inhibitory effect of the investigated composites against E. coli and S. epidermidis. Whereas M. luteus was inhibited only by the higher concentration of chitosan in the tested composites, inhibition was not found against C. krissii and all tested filamentous fungi.

“…Magnetic biosorbents made from sonication of a mixed EFB, EFB celluloses and kapok fibre can be used to remove heavy metal ions in wastewater treatment (Daneshfozoun et al, 2017). Chitosan composite film reinforced with cellulose from EFB performed well for cadmium ion removal (Rahmi et al, 2017). Lignins serve as a suitable green material for phenolic resins production (Faris et al, 2017).…”

Oil palm (Elaeis guineensis Jacq.) has emerged as a major economic crop feeding the world today. This article aims to capture the more recent progress made by the oil palm industry and to discuss the possible path research and development will take in the coming years. In 2017, palm oil and palm kernel oil production recorded close to one-third (75.17 million tonnes) of world total oils and fats production from a planted area of 19.04 million hectares, mainly from Indonesia and Malaysia. Malaysian palm oil alone fetched RM 46.12 billion export revenue from its India and European Union markets. The continuous growth of the industry is made possible through implementation of key strategies covering the whole process chain, from upstream to downstream. Intensified mechanisation, integrated pest and Ganoderma management, advanced breeding and biotechnology as well as good agricultural practices help boost oil palm yields for both plantations and smallholdings. In the palm oil milling sector, focus such as by-products valorisation, biogas (productivity, trapping and utilisation as a form of energy) and wastewater management, i.e. palm oil mill effluent for final discharge compliance ensures that the industry meets its sustainable goals. Palm oil is generally used for edible purpose, however about 20% goes into higher value non-food applications such as palm biodiesel.The beneficial nutritional aspects of palm oil are evident based on its positional distribution and fatty acids composition, while its quality enhanced via technology integration/mitigation and analytical elucidations.Facing strong competition from petrochemicals, palm-based oleochemicals are strategically aimed at producing value-added products for niche and new markets. It is apparent that synergising conventional and disruptive technologies at every level of the palm oil supply chain is desirable and essential to thrust the industry forward. As a commodity, palm oil has not only emerged as an important food source, but has proven to be effectively utilised for feed, fuels and chemicals, to name a few, in developing a sustainable and balanced circular economy.
