“…BB and BFB demonstrated semicrystalline structures with specified cellulose structure peaks of 16.62, 22.34, and 34.34° for BB and specified SiO 2 peaks of 20.94, 26.78, and 50.32° for BFB, as shown in Figure 2 a,b, respectively. 11 , 23 Moreover, it was also found that the specified sodium alginate peaks of 13.54, 18.58, 21.82, and 38.26° resulted from bead formations. 24 BBF and BFBF not only exhibited the specified peaks similarly to BB and BFB but also displayed the specified iron(III) oxide-hydroxide peaks of 21.40, 33.28, 36.84, 41.50, and 53.84° related to JCPDS:29-0713, 25 resulted from adding iron(III) oxide-hydroxide to BP and BFP before synthesizing bead materials, shown in Figure 2 c,d, respectively.…”

“…Moreover, the cost–benefit management is also required for industrial applications, so low-cost adsorbents from waste materials might be a good choice to control the operation cost. Many research articles have used various waste materials such as sawdust, coconut shells, potato peels, banana peels, rice husk, bagasse, and bagasse fly ash for dye removal in wastewater. − Among these, bagasse and bagasse fly ash are interesting choices because not only they have good chemical properties of cellulose, lignin, and hemicellulose for dye removal but also they help reduce a huge amount of agriculture or industrial waste by acting as recycled waste for the wastewater treatment.…”

Dye contamination in wastewater affects the photosynthesis of aquatic plants and algae by blocking the sunlight, and it induces toxicity to aquatic organisms, which might result in human health effects. Thus, the treatment of dyes in wastewater is required before discharging into the receiving water for safety purposes. Six dye adsorbent materials bagasse beads (BB), bagasse fly ash beads (BFB), bagasse beads with mixed iron(III) oxide-hydroxide (BBF), bagasse fly ash beads with mixed iron(III) oxide-hydroxide (BFBF), bagasse beads with mixed zinc oxide (BBZ), and bagasse fly ash beads with mixed zinc oxide (BFBZ) were synthesized and investigated using various characterization techniques such as X-ray diffractometry (XRD), field emission scanning electron microscopy with focused ion beam (FESEM-FIB), energy dispersive X-ray spectrometry (EDX), and Fourier transform infrared spectroscopy (FTIR). A series of batch experiments on the effects of dosage (0.5–3 g), contact time (3–18 h), temperature (30–80°C), pH (3–11), and initial concentration (30–90 mg/L) were used to investigate reactive blue 4 (RB4) dye removal efficiencies in aqueous solution, and their adsorption isotherms and kinetics were studied for explaining their adsorption patterns and mechanisms. All dye adsorbent materials demonstrated semicrystalline structures, and their surface morphologies had a spherical shape with coarse surfaces. Five main elements of oxygen, carbon, calcium, chlorine, and sodium and six main functional groups of alcohol and carboxylic acid (O–H), carbon dioxide (O=C=O), aromatic groups (C=O and N=O), alkene (C–H), and sodium alginate (C–O–C) were detected in all dye adsorbent materials. For batch tests, they could remove RB4 dye by more than 90%, and BFBF exhibited the highest RB4 dye removal efficiency at 99.36%. Freundlich and pseudo-second-order kinetic models well explained their adsorption patterns and mechanisms, in which BFBF demonstrated a higher maximum adsorption capacity ( q m ) of 10.277 mg/g than that of other dye adsorbent materials. Therefore, all dye adsorbent materials offer good potential for further industrial applications.

“…Before the treatment of cationization, exposure to plasma nitrogen was successful ineffective PET coloring, which resulted in nitrogen being selected as a working gas with a flow rate of 3 liters/ min [58]. The results also indicated that PET fabric with a very effective surface was achieved by combining the nitrogen plasma and cationization process, leading to better color, weight resilience, traction strength, and ruggedness [57].…”

“…The study is based on the application of an environment-friendly and cationizing effective plasma technology to enhance the hydrophobic nature of polyester (PET) by integrating hydrophilic functions on the PET surface [57]. The results of the study Before cationization with a quaternary ammonium salt, the PET surface was treated firstly with three distinct plasma gases (Quat 188) [58]. In both dyeing and printing operations, madder roots were employed for natural dyes for the green color of PET materials.…”

P LASMA treatment for almost all synthetic and cellulosic textiles is considered to be one of these physical technologies. Plasma treatment does not involve the treatment of hazardous chemicals and thus, compared to chemical treatment, there are no problems with effluents. The study demonstrated that most types of materials (natural synthetics and blends) with natural dye using pigment printing techniques can be printed using high-quality plasma radiation. It is an environmentally friendly process, fast-growing, and finds certain potential applications. The study claims that polyester plasma therapy and surface modifications can alleviate difficulties with printing. The study investigates the treatment of a PET fabric with an efficient plasma approach to activate the surface before cationization treatment.

Purpose This paper aims to focus on studying the batch desorption of adsorbed crystal violet (CV) from date stones (Phoenix dactylifera), untreated (UDS) and treated using NaOH (TDS). Design/methodology/approach The process variables such as different desorbing agents, volume and concentration of the desorbing agent, contact time, dye concentration before adsorption and temperature affecting CV desorption from CV-loaded untreated date stones (CV@UDS) and treated adsorbent (CV@TDS) were optimized. The UDS and TDS were regenerated using 0.6 m HCl as eluent. Findings The HCl solution was an excellent eluent for the CV desorption from CV@UDS (96.45%) and CV@TDS (98.11%). The second-order model and the Langmuir model well exemplified experimental data with maximum desorption capacities were 63.29 mg g−1 for the CV@UDS and 243.90 mg g−1 for the CV@TDS. The calculated thermodynamic showed that the CV desorption was spontaneous, endothermic and physical. Good regeneration and reusability of UDS and TDS for the CV removal for four consecutive adsorption–desorption cycles. Practical implications This study provided a good example of reusing UDS and TDS with NaOH for fast removal of a toxic organic pollutant, CV from the wastewaters. Originality/value The use of UDS and TDS with NaOH for the first time for desorption study and their reusability to removing CV from their aqueous solutions.
