“…On the other hand, the design and the use of various functional biomaterials for drug loading and release in the development of electro‐stimulated drug release devices have become in a promising trend using bacterial cellulose or chitosan nanocapsules . Green adsorbents based on cellulose or carbon nanocomposites are another promising area . During the recent years, a noticeable growth in the demand of wearable bioelectronic devices, which can monitor motions, was registered.…”

This work investigates the valorization of sodium lignosulfonate, kraft, and organosolv lignins from South America. A detailed characterization of the lignins and their chemical modification by hydroxymethylation through its reaction with formaldehyde were performed. The characterization included measurements of moisture, ash, carbohydrate contents, elemental and thermogravimetric analysis, and functional groups, molar mass distributions by Fourier transform infrared spectroscopy, and size exclusion chromatography, respectively. Also, reactive aromatic hydrogens ( H Ar ) were quantified by the measurement of phenolic hydroxyl groups (P-OH) content by UV-Vis spectroscopy. The different initial formaldehyde/lignin weight ratios (0.07, 1.47), temperatures (40, 50, and 70 C), and pHs (9, 11); and the following of hydroxymethylation reactions by UV-Vis spectroscopy were investigated. All lignins resulted attractive for the use as replacement of phenol in phenolic resins, but sodium lignosulfonate was the most appropriate due to its water solubility.

“…The adsorbent was fabricated by modification of 3-aminopropyltrimethoxysilane (3-APTS) on the surface of hollow glass microspheres (HGMs) by a dehydration reaction between hydroxyl groups, and coated with sodium alginate to prevent aggregation. Compared with other biomass templates for the synthesis of composite material, just like cellulose (Zhang et al 2019a) and yeast (Zhao et al 2018), sodium alginate contained a large number of carboxyl groups and had biocompatibility, biodegradability, and non-toxicity (Ma et al 2019). The solid-phase extraction adsorbent ALG/3-APTS/HGMs (sodium alginate-coated HGMs modified with 3-APTS) can be used to enrich and separate anionic dye.…”

A buoyant solid-phase extraction adsorbent was prepared by sodium alginate-coated hollow glass microspheres (HGMs) modified with 3-aminopropyltrimethoxysilane (3-APTS) for the separation and enrichment of anionic dye amaranth. After adsorbing amaranth, these low-density adsorbents can float on the surface of the solution, so the separation between adsorbents and substrates can be carried out by flotation. Quantitative determination of amaranth after separation and enrichment can be achieved by combining spectrophotometry. Under the optimum conditions, the linear range and detection limit for amaranth detection were 0.02 mg L −1-2.0 mg L −1 and 0.0021 mg L −1 , respectively. The proposed method was applied to the determination of amaranth in different beverages, and the results were in good agreement with those by high-performance liquid chromatography (HPLC). The recoveries of amaranth in different beverages were between 97.93 and 105.91%. The floating adsorbent can be used as a conventional sample preparation method for the detection of low concentration analytes in complex samples.

“…Adsorption, 6 7 8 centrifugation, membrane separation, chemical demulsification, 9 10 11 chemical oxidation, coagulation and electrochemical methods are normally exploited to remove oil from polluted water. Among them, adsorption has become a research hotspot with the characteristics of high oil removal efficiency, no secondary pollution, simple processing, 12 low energy consumption and low operation cost. The adsorbents 13 widely used in oily wastewater treatment include activated carbon, 14 15 16 17 polyethylene, fly ash, bentonite, carbon fiber and super oil- 18 adsorbing resin.…”

“…Therefore, graphene oxide (GO) is often prepared for further usage because the introduction of polar oxygen-containing 22 groups and defects could make it to exhibit a better processibility. Recently, aerogel has gradually attracted attentions due to its unique properties, such as high porosity, high specific surface area, low thermal 12,23 conductivity and ultra-low density. Among them, reduced GO aerogel has a large specific surface area and extremely hydrophobic characteristics to ensure the efficiency for the separation of oil and organic solvents from water, so it has been widely studied in the removal of oil and organic 24 solvents from sewage.…”
