“…Then, the residue was further treated with an alkali. In that process, the hemicellulose and a small amount of lignin can be removed . Before the adsorption experiment, the elemental composition, FTIR spectra, and solid-state 13 C NMR spectra were acquired to characterize the differences between root individual components.…”

The behavior of organophosphate esters (OPEs) in plants has drawn considerable attention because of their adverse effects to biota. However, the root uptake pathways and cell wall accumulation mechanisms of OPEs in plants are still unclear. In this study, the uptake pathways, subcellular distribution, and accumulation mechanisms of OPEs in wheat roots were elucidated. The results demonstrated that the symplast is the major pathway for uptake of both tris(2-chloroethyl) phosphate (TCEP) and triphenyl phosphate (TPHP) in wheat roots. Inhibitor experiments showed that the transmembrane transport of OPEs is a passive uptake process, and aquaporins and carrier proteins contribute to the uptake of OPEs. More than 69% of TCEP was accumulated in cell sap due to its high hydrophilicity, while the hydrophobic TPHP was mainly stored in the root cell wall. The sorption affinity of TPHP decreased gradually following the sequential fractionation of wheat roots, which confirmed the significant contribution to TPHP sorption on wheat roots. A significant positive correlation between the sorption affinity values and the percentage of aromatic carbon was observed (r 2 = 0.856, p < 0.01), indicating that the accumulation of hydrophobic OPEs in roots does not just depend on lipids alone, but the aromatic moieties of lignin in the cell wall also contribute to OPE accumulation.

“…Regardless of the amount of NaOH and the pretreatment time, there was still around 10% lignin in the pretreated sample. Alkaline hydrolysis degrades hemicellulose and lignin by destroying the aryl–ether, carbon–carbon, and aryl–aryl bonds and the ester bonds between lignin and hemicellulose. − The bulging fibers induce dissolution of both hemicellulose and lignin. The effect of treatment time is shown in Figure b, and it can be observed that when the treatment time is increased from 20 to 30 min with a concentration of NaOH of 2 w/w %, there is a noticeable change, but there is little change when the time is increased to 40 min.…”

Cellulosic aerogel from water hyacinth (WH) was synthesized to address the dual environmental issues of water hyacinth pollution and the production of a green material. Raw WH was treated with sodium hydroxide (NaOH) with microwave assistance and in combination with hydrogen peroxide (H 2 O 2 ). The results from X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, and scanning electron microscopy (SEM) showed that lignin and hemicellulose were markedly decreased after treatment, reducing from 24.02% hemicellulose and 5.67% lignin in raw WH to 8.32 and 1.92%, respectively. Cellulose aerogel from the pretreated WH had a high porosity of 98.8% with a density of 0.0162 g•cm −3 and a low thermal conductivity of 0.030 W•m −1 •K −1 . After modification with methyl trimethoxysilane (MTMS) to produce a highly hydrophobic material, WH aerogel exhibited high stability for oil absorption at a capacity of 43.3, 43.15, 40.40, and 41.88 (g•g −1 ) with diesel oil (DO), motor oil (MO), and their mixture with water (DO + W and MO + W), respectively. The adsorption remained stable after 10 cycles.

“…This large reduction in the contents of hemicellulose and lignin may have been due to the porous structure of the water hyacinth fibers, which facilitated the ingress of the alkaline solution. During the alkaline treatment, the fibers swelled, causing the solubilization of both hemicellulose and lignin and cleavage of the α-ether linkages and ester bonds between the lignin and hemicellulose . A longer treatment time and a higher alkaline concentration resulted in the elimination of more lignin.…”

The extraction of cellulose nanofibers (CNFs) from a lignocellulosic source containing less lignin would be an effective way to avoid repetitious and energy-consuming chemical treatments. In the present study, we used water hyacinth (Eichhornia crassipes)a fast-growing, rapidly reproducing, sustainable, and inexpensive raw material with a low lignin content (4.1%)to successfully prepare CNFs with diameters of 10–30 nm and lengths of several μm. We used three different chemical approaches: chemical-free, alkaline, and combined sodium chlorite and alkaline treatments. The results indicate that the alkaline treatment alone was sufficient to eliminate most of the lignin and hemicellulose from water hyacinth, providing CNFs with morphological, crystallinity, and thermal characteristics similar to those of CNFs prepared using combined sodium chlorite and alkaline treatment. Also, mechanical properties and thermal expansion of the nanopapers prepared from these chemically treated CNFs were comparable. Water hyacinth has potential as a sustainable cellulose source for the large-scale production of CNFs for advanced applications in tropical and subtropical countries in comparison with wood or other lignocellulosic sources due to a lower requirement for chemical treatments. Moreover, water hyacinth has other positive aspects such as its rapid breeding rate, availability, and economical price.
