“…Consequently, this focus has led to further research on the specifi c characterization of individual plant fi bers such as bamboo, okra, sisal, and henequen (Mishra et al, 2004; Bé-akou et al, 2008;De Rosa et al, 2010;Liu et al, 2012;Arrakhiz et al, 2013) and studies on composite materials (Mohanty et al, 2002;Herrera-Franco and Valadez-González, 2005;Faruk et al, 2012). However, fi bers from Agave plants have been little studied: of the 256 recorded species, only a handful have been thoroughly analyzed, most notably A. fourcroydes, A. salmiana, A. sisalana, and A. tequilana (Li et al, 2000;Piven et al, 2001; Iñiguez et al, 2005;Velázquez-Jiménez et al, 2013).In general, information reported regarding the harvesting of the agave, using the by-products and plant parts, and characterizing the plant is very limited. Hence, many areas still need to be investigated.…”

Abstract:The main aim of this study was to characterize cooked bagasse fi bers from Agave angustifolia Haw. The fi bers were characterized using scanning electron microscopy, differential scanning calorimetry, thermogravimetric analysis, X-ray Diffraction and chemical analysis. The tensile strength was also tested using fi bers with a uniform length (30 mm). The fi bers were light brown in color, with a mean diameter and length of 501 μm and 144 mm, respectively. Scanning electron microscopy images revealed elliptically shaped cells with varying lumen size. Holocellulose content was approximately 82.12 %, and total lignin content was approximately 20.69 %. Due to the crystallinity and lignin content, the fi bers proved to be thermo-stable until 220 °C.The mean values of tensile strength, Young's modulus, % strain (ε), and ultimate tensile strength were determined via mechanical tests. The results are comparable to those of other common lignocellulosic fi bers, confi rming their potential use as a reinforcing element in a polymer matrix to form a new biodegradable composite. Keywords: chemical composition, crystallinity, mechanical tests, morphology, thermal analysis Resumen: El objetivo principal de este estudio fue caracterizar las fi bras de bagazo cocido de Agave angustifolia Haw. Las fi bras fueron caracterizadas a través de microscopia electrónica de barrido, calorimetría diferencial de barrido, análisis termogravimétri-cos, difracción de rayos X y análisis químico. También se realizaron pruebas de resistencia a la tracción usando fi bras de longitud constante (30 mm). Las fi bras presentaron un color marrón claro, con diámetro medio de 501 μm y longitud media de 144 mm. Las imágenes del microscopio electrónico de barrido mostraron células de forma elíptica con diferente tamaño de lumen. El contenido de holocelulosa fue alrededor de 82.12 % y el contenido total de lignina de aproximadamente 20.69 %. La fi bra resultó ser térmicamente estable hasta 220 °C debido a la cristalinidad y el contenido de lignina. El esfuerzo de tensión, el módulo de Young, el porcentaje de deformación (ε) y el esfuerzo último de tensión fueron obtenidos de las pruebas mecánicas. Los resultados son comparables a los de otras fi bras lignocelulósicas comunes, lo cual confi rma que estas fi bras tienen potencial como refuerzo en una matriz polimérica para formar un nuevo compuesto biodegradable. Palabras clave: análisis térmico, composición química, cristalinidad, morfología, pruebas mecánicas. ETHNOBOTANY R ecently, research on plant fi bers has been increasing due to the abundance of these materials and their status as renewable resources (Joseph et al., 1999;Ghali et al., 2006;Lucena et al., 2009;Ku et al., 2011;Kestur et al., 2013). Consequently, this focus has led to further research on the specifi c characterization of individual plant fi bers such as bamboo, okra, sisal, and henequen (Mishra et al., 2004; Bé-akou et al., 2008;De Rosa et al., 2010;Liu et al., 2012;Arrakhiz et al., 2013) and studies on composite materials (Mohan...

“…The use of these residues has, in general, given the process the more common name of biosorption with the adsorbent nominated as biosorbent. Various biosorbents developed from agrowastes and used for heavy metals removal include rice straw (Gao et al 2008), free algal biomass for biosorption of copper and zinc (Wan Maznah et al 2012), removal of copper and zinc sunflower (Helianthus annuus), Chinese cabbage (Brassica campestris), cattail (Typha latifolia), and reed (Phragmites communis) as reported by Yeh et al (2011), biomass of Desmostachy bipannata (Kush, a religious plant of Hindus) (Kour et al 2012), peanut shell (Witek-Krowiak et al 2011), Peganum harmala seeds as a biosorbent to remove lead, zinc and cadmium ions from contaminated water (Zamani et al 2013), seaweed (Basha et al 2008), wood and bark (Mohan et al 2007), tea waste (Malkoc and Nuhoglu 2007), maize corn cob, jatropha oil cake, sugarcane bagasse (Dos Santos et al 2011), raw and treated Agave salmiana bagasse (Velazquez-Jimenez et al 2013), sawdust (Hashem et al 2013;Memon et al 2005), rice husk (Kumar and Bandyopadhyay 2006), marine algal biomass, bagasse fly ash (Rameshraja et al 2012), wool, olive cake, sawdust, pine needles, Aleppo pine adsorbent (Benyoucef and Amrani 2011), almond shells, impregnated palm shell activated carbon with polyethyleneimine (Owlad et al 2010), Camellia oleifera Abel shells (Lu et al 2013), cactus leaves, and charcoal and pine bark (Al-Asheh et al 2000).…”

This paper reports the potential of chemically treated wood chips to remove copper (II) ions from aqueous solution a function of pH, adsorbent dose, initial copper (II) concentration and contact time by batch technique. The wood chips were treated with (a) boiling, (b) formaldehyde and (c) concentrated sulphuric acid and characterized by Fourier transform infrared spectroscopy, scanning electron microscopy and energy dispersive analysis X-ray. pH 5.0 was optimum with 86.1, 88.5 and 93.9 % copper (II) removal by boiled, formaldehyde-treated and concentrated sulphuric acid-treated wood chips, respectively, for dilute solutions at 20 g L -1 adsorbent dose. The experimental data were analysed using Freundlich, Langmuir, Dubinin-Radushkevich and Temkin isotherm models. It was found that Freundlich and Langmuir models fitted better the equilibrium adsorption data and the adsorption process followed pseudo-second-order reaction kinetics. The results showed that the copper (II) is considerably adsorbed on wood chips and it could be an economical option for the removal of copper from aqueous systems.
