“…However, the current results obtained indicated that the removal of both dyes was more favorable in acidic condition and this agreed well with some of the previously reported works. [19][20][21] The high affinity shown by the films in acidic pH can be attributed to the usage of chitosan as the supporting matrix in this study. At lower pH, amino groups of chitosan can be easily protonated to form -NH 3 + .…”

The effectiveness of using TiO 2 and corn cob films to remove Malachite Green oxalate (MG) and Acid Yellow 17 (AY 17) from binary dye solution was studied. The immobilization method in this study can avoid the filtration step which is not suited for practical applications. Batch studies were performed under different experimental conditions and the parameters studied involved initial pH of dye solution, initial dye concentration and contact time and reusability. The equilibrium data of MG and AY 17 conform to Freundlich and Langmuir isotherm model, respectively. The percentage removal of MG remained high after four sorption cycles, however for AY 17, a greater reduction was observed. The removal of both dyes were optimized and modeled via Plackett-Burman design (PB) and Response Surface Methodology (RSM). IR spectrum and surface conditions analyses were carried out using fourier-transform infrared spectrophotometer (FTIR), scanning electron microscope (SEM) and atomic force microscope (AFM), respectively.

“…As can be seen from Figure 8 a, fly ash is a kind of semi-transparent glass microspheres whose surface is adhered to more small spherical particles. There are gaps and small holes between the ball-shaped particles that facilitate the adsorption property of fly ash [ 35 , 36 ]. As shown in Figure 8 b, the FA particles are distributed quite uniformly in the PAA-AM macromolecule network.…”

Solution polymerization synthesized alt-resistant superabsorbent poly (acrylic acid-acrylamide/fly ash) composites. The mass ratio of acrylic acid (AA) to acrylamide (AM), the concentration of crosslinker, the neutralization degree (ND) of AA, and the polymerization temperature were investigated by single-factor method. Optimized conditions for the synthesis of poly (acrylic acid-acrylamide/fly ash) (PAA-AM/FA) are, as following: m (AA)/m (AM) is 1.5, the content of crosslinker N, N-methylenebisacrylamide. (MBA) is 0.7%, neutralization degree of AA is 70%, polymerization temperature is 70 °C, and fly ash (FA) content is 50%. The prepared PAA-AM/FA demonstrated superior water absorption performance. The absorption capacities of PAA-AM/FA for pure water and 0.9% NaCl solution were found to be 976 g·g−1 and 81 g·g−1, respectively. Furthermore, PAA-AM/FA was found to have excellent adsorption capacity (148 mg·g−1) for Rhodamine B in water. Fourier Transform-Infrared Spectroscopy (FT-IR), Thermogravimetric Analysis (TGA), and Scanning Electron Microscopy (SEM) characterized the prepared materials. Results showed that fly ash was incorporated into the macromolecular polymer matrix and played a key role in improving the performance of the polymer composites.

“…The adsorbent materials can be classified into: (a) mineral supports such as activated carbon, (b) vegetal material, such as sunflower stalks and (c) modified biopolymers such as aminated sawdust and cellulose bearing active groups [9]. Various dye adsorbent substrates were used including: peels [10], activated carbon [11], soil [12], fly ash [13], silica [14], chitosan and chitosan derivatives [15][16] and the modified cellulosic materials [17]. The adsorption efficiency of the different adsorbents towards the dye from aqueous solution could be affected by many factors such as the pH [18][19][20], the dye concentration in the aqueous solution [20,21], the ionic strength of the dye solution [19,22], contact time [20,21] and the temperature of the dye aqueous solution [22].…”

“…There are different applications of the irradiation process, especially on the polymeric materials, either trough its polymerization and crosslinking effects, or by introducing new functionalized reactive groups upon the irradiated materials [23][24][25]. For example, the irradiation can be used to modify the cellulosic substrates to gain new properties as dye absorbents, which help in the dye removal and play an important role in the decreasing of the water pollution, especially in the textiles wastewater [17].…”

Jute fibers were graft-copolymerized with acrylonitrile using gamma radiation technique. The nitrile groups attached to the grafted fibers were converted into amidoxime groups, through an amidoximation process, for using as an adsorbent for the acid dyes from the textile wastewater. The graft yield as a function of the irradiation dose was investigated. The amidoximated Jute fibers were characterized by Fourier transform infrared (FTIR) and X-ray diffraction (XRD). The thermal stability of modified Jute fibers was also investigated by thermogravimetric analysis (TGA). The kinetic parameters of the adsorption process and the effective conditions on the adsorption capacity, such as the pH and contact time, were also investigated. The grafting of the Jute fibers with ACN and the amidoximation process of the nitrile groups were confirmed using FTIR technique. The results indicated that, the dye adsorption was enhanced at low pH of 4 and obeyed the pseudo second order kinetic model.
