“…4. It can be seen that all samples exhibited cellulosic form, characteristic of native cellulose in lignocellulosic materials with a clear dominance of the beta I allomorph [29,37]. The diffraction intensity increased for SSM and SMM compared to untreated sawdust samples due to the reduction of hemicelluloses upon treatment.…”

“…Likewise it is also observed that non-thermal plasma treatment deformed exterior ribs and the deteriorated the surfaces of SMM and SSM. This is due to the fact that reactive species (peroxides, anions and superoxides) generated during the plasma discharge act in the breakdown of structurally important bonds of extractables [46]. As a result, there is separation of the cell layers and consequently the extravasation of essences and resins.…”

The Removal of an anionic Reactive Blue 2 (RB2) dye in an aqueous solution was successfully achieved using a plasma-modified agricultural biomaterial waste. Sawdust from Moabi (Baillonellatoxisperma) and Sapelli (Entandrophragmacylindricum) was modified using non-thermal gliding arc plasma. The natural raw materials and plasma treated were characterized by Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA), Scanning Electron Microscopy (SEM), XRD, Chemical analysis by Fluorescence, Sorption Analyser, and Zetametry. Experimental parameters such as initial pH, contact time, adsorbent dose, initial RB2 concentration, and temperature were optimized. The results showed that the removal of Reactive Blue 2 dye was favorable at acidic pH conditions with the maximum capacity going from 172,85 to 200,91 mg.g-1 to 98,19 and 149,02 mg.g-1 respectively for raw and plasma-treated Sapeli and Moabi. The Avrami fractional-order kinetic provided the best fit to the experiments data and the thermodynamic adsorption data of untreated (SSB and SMB) and plasma-treated (SSM and SMM) sawdust followed an exothermic process. This work demonstrated that non-thermal plasma modified wood sawdust can be a good alternative absorbent for the removal of dye pollutants from an aqueous solution.

“…In recent years, the low cost adsorbents based on natural bers have been recognized as e cient, cost-effective, and environmental friendly for contamination removal purposes (Candido et al,2021). Owing to small ber diameter and excellent osmotic stability, the plant based cellulose bers have been widely investigated for the adsorption of pollutants, including radionuclides (Bai et al, 2020;Li et al, 2020), heavy metals (Huang et al, 2021;Pang et al, 2020), humic acid (Du et al, 2019), phosphate (Du et al, 2019), dyes (Shao et al, 2021), gold ions (Mostofa et al, 2021) and oil/water separation (Meng et al, 2020;Liu et al,2018) et al Plant-based cellulose bers such as sisal, jute, hemp, coir, kapok, cattail, and cotton linter display lots of advantages over synthetic bers like low-cost, low density, biodegradability, recyclability, environment friendly, and less hazardous over synthetic bers (Chokshi et al, 2020;Cui et al, 2021;Zheng et al, 2020;Silva et al, 2020). Among them, sisal ber (SF) is a most noteworthy and industrially promising bers have attracted particular interest due to its fairly coarse, moderate high speci c strength and stiffness, durability, and resistance to deterioration in saltwater (Tesfamariam et al, 2019).…”

“…The modi cation of ber matrix has attracted increasing attention, which are relevant strategies to improve the adsorption performance of plant bers. Various methods such as carbonization (Melike et al, 2018), plasma treatment (Silva et al, 2020), chemical deposition (Tesfamariam et al, 2019), microwave treatment (Gao et al, 2015) and electron or γ-ray radiation techniques (Dong et al, 2021) are used for ber modi cation. Speci cally, radiation-induced graft polymerization (RIGP) can conveniently introduce the required functional groups onto polymer surface and then endow the polymers with densely accessible adsorption sites ( Du et al, 2018).…”

The removal of Indigo carmine (IC) from the aquatic environment is necessary due to its high toxicity. In this study, methacryloxy ethyltrimethyl ammonium chloride (DMC) modified sisal fiber (SF-DMC) was prepared by a one-step process using radiation induced grafting polymerization. The adsorption performance of SF-DMC toward IC dye was investigated by batch adsorption experiments. The adsorption kinetic studies shows that adsorption equilibrium reached within 30 min, and it can be well described by pseudo-second-order model. The adsorption isotherms are well described by Langmuir model, and the theoretical maximum adsorption capacity are 709.22 to 892.86 mg/g at different temperature. The adsorption of IC onto SF-DMC is a spontaneous and exothermic reaction and low temperature is favorable for adsorption. Besides, SF-DMC has good selective adsorption for IC in the mixed anionic dyes and in high-salt solution. The dyes on SF-DMC can be desorbed by 2mol/L HCl solution. Therefore, the SF-DMC exhibits excellent adsorption performance, which is suitable for IC removal from high-salt wastewater.

“…Plasma treatments are an interesting ecological and innovating alternative to modify the surface properties of a given substrate. A plasma is an ionized gas that can have different effects on the processed substrate, including ablation, crosslinking, roughness modification or surface activation [11][12][13][14][15][16]. Different gases can be used as well as different temperature and pressure conditions to achieve the desired effects.…”

An environmentally friendly approach, which consists in coupling a dielectric barrier discharge (DBD) based atmospheric plasma treatment with a coating of an aqueous phase polyurethane dispersion (PUD) containing blocked polyisocyanates, is proposed to improve the adhesion of a thermoplastic polyurethane (TPU) film onto a poly-(ethylene terephthalate) (PET) textile fabric. In this study, a screening digital design of experiment plan (DOE) was developed to determine the influence of process parameters on the adhesion between film and fabric and to evaluate the best possible adhesion value. The process parameters considered are: the dielectric barrier discharge power, the speed of the fabric undergoing the treatment, the concentration of polyisocyanates (NCO) in the PUD and the air gap. The adhesion was measured by a peeling test and further scanning electron microscope observations were carried out. Results showed that an increase of both the processing power and the NCO content in PUD, as well as the decrease in the DBD speed, had a positive effect on the adhesion. In addition, X-ray photoelectron spectroscopy and contact angle measurements demonstrated an increase in the oxygen/carbon atomic percentage ratio between the reference fabric and the treated fabric. Thus, the calibrated oxidation of the PET treated with DBD plasma treatment leads to a greater chemical and physical interaction with the TPU film, which results in better film-fabric adhesion.
