“… 57 The main mechanism of RB4 dye adsorption on dye adsorbent materials might contain three possible reactions, which were electrostatic attractions, hydrogen bonding interactions, and n−π bonding interactions. 39 For electrostatic interactions, RB4 dye molecules with negatively charged sulfonate groups (−SO 3 – ) interacted with the positively charged hydroxy group (−OH) on the surfaces of dye adsorbent materials at acid pH (pH < pH pzc ), 58 their pH pzc values are reported in Figure 6 . For hydrogen bonding interactions, the hydrogen ions (H + ) of the hydroxyl group (−OH) in dye adsorbent materials reacted with the nitrogen (N) of the dye molecule for RB4 dye removal.…”

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.

“…Remarkable improvement of adsorption capacity for the PEI‐impregnated‐ABF powder partly arises from the small size (powder form) material with increasing surface area. In case of PEI‐CW 56 and PEI‐coated‐sugarcane bagasse, 57 dyed with Reactive black 5 (RB5), relatively low dye‐adsorption capacity is observed ( q e,exp = 25 mg/g). It is observed that, for the latter systems, PEI‐CW is more effective in removal of RB5 than CR dye, due to the presence of four negatively‐charged sulfonate groups in RB5 dye structure, which can form stronger electrostatic interaction with the adsorbent.…”

Immobilization of polyethyleneimine (PEI) on bamboo viscose fiber using epichlorohydrin (ECH) crosslinker (ABF‐e‐PEI) was employed to enhance the ability of dyeing with lac. The results from morphological observation, thermal degradation behavior, Fourier transform infrared (FTIR) analysis, x‐ray photoelectron spectroscopy (XPS) and x‐ray diffraction (XRD) clearly revealed the success of PEI‐immobilizing on fiber surface with no significant change in intrinsic properties of the fiber after modification. The modified fiber exhibited fast and efficient adsorption with the adsorption capacity >90 mg/g which was much higher than that of the unmodified adsorbent (did not exceed 10 mg/g). The results from kinetic and isotherm studies showed that the adsorption process conformed to the pseudo‐second‐order, intra‐particle diffusion and Langmuir models. Adsorption temperatures have less effect to the adsorption performance of the modified adsorbent. Electrostatic ion‐dipole interaction between protonated amines of PEI and negative charged sites of lac dye was the main proposed mechanism. Good resistance of color changes for ABF‐e‐PEI was confirmed by the color‐fastness assessment (grade 4–5), suggesting efficient method of PEI‐immobilizing using ECH crosslinker. The binding reaction of between amine groups of PEI and hydroxyl groups of the cellulosic fiber using ECH crosslinker can be expected to have a broad potential application in dyeing processes or pollution treatments due to its simple, cost‐effective, flexible and efficient method.

“…On the cocoa husk, the strong absorption band at 3366.4 cm -1 defines the amino functional groups. The modification of cacao shell as a biomaterial produces amino groups [37][38][39]. According to Vieillard, 2018 [38] modification of cacao shell through amino grafting shows a higher CO 2 retention capacity compared to metal-free products, although its alkalinity and porosity are lower.…”

Environmental pollution by phosphate and nitrate ions has become a serious problem. The innovation of cacao husk as an adsorbent and sustainable material can be a solution for absorbing phosphate and nitrate ions. Cocoa husk (CH) derived from the matured cocoa fruit's remaining pod material that often discarded as waste. The aim of this research is to develop an environmentally friendly and economical cacao husk (CH) based material for the absorption of phosphate and nitrate ions from aqueous solutions. CH surface modification is made by reacting the cationic polymer 2-[(methacryloyloxy)ethyl]trimethylammonium (META), into CH treatment (CH-T). Successful surface modification of CH-T with cationic polymers was confirmed to improve the surface properties for the removal of phosphate and nitrate ions. The surface charge morphology, structure, pore distribution and stability of the modified CH-T were investigated by Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), Branueur-Emmet-Teller (BET) and elemental analysis. 0.3 grams of CH-T modified with 75% cationic polymer with stirring at 70 rpm for 180 minutes at 50°C was reported as the best modification condition. Removal efficiencies of phosphate and nitrate ions increased after adding quaternary ammonium to CH-T to 96% and 93.4%, respectively. These results indicate that CH modification has prospective as a low-cost catalyst for wastewater treatment.
