Synthesis of polyamidoamine dendrimer (PAMAM/CuS/AA) nanocomposite and its application in the removal of Isma acid fast yellow G Dye

Abstract

The adsorption of Isma acid fast yellow G dye was studied using polyamidoamine (PAMAM)/Copper sulfide (CuS)/AA nanocomposite containing different amounts of CuS by batch technique. PAMAM dendrimer/CuS/AA nanocomposites were synthesized via gamma irradiation cross‐linking method with the aid of sonication. The nanocomposites were characterized by Fourier‐transform infrared, X‐ray diffraction, transmission electron microscope, energy dispersive spectroscopy X‐ray, thermal gravimetric analysis, ultraviolet‐visible, and fluorescence spectroscopy. The size of the CuS nanoparticles was formed in the range of 12–19 nm. The adsorption capacity of the nanocomposites was evaluated as a function of initial dye concentration, pH, adsorbent dosage, and time. It was verified that the adsorption rate fits a pseudo‐second‐order kinetics for initial Isma acid fast yellow G dye concentrations. Results indicated that the adsorption of Isma acid fast yellow G dye fitted well to the Langmuir model. Our results demonstrate that the PAMAM dendrimer/CuS/AA nanocomposite is very promising for removing organic dyes from wastewater. Copyright © 2015 John Wiley & Sons, Ltd.

Photocatalytic Degradation of Rhodamine B Dye in Wastewater Using Gelatin/CuS/PVA Nanocomposites under Solar Light Irradiation

“…In a typical method, gelatin/CuS/PVA nanocomposites were prepared according to the method reported in previous work by Abou Taleb, et al [20]. In Particular, 0.3 g of gelatin was dissolved in 30 ml of distilled water under ultrasonic stirring for 1 h at room temperature to form an aqueous solution of 1% concentration.…”

“…The application of natural organic substances in the preparation of nano-sized material introduces a cutting edge for the charge transfer resulting in major enhancement of photocatalytic efficiency [18] [19]. Aboutaleb, et al [20] prepared PAMAM dendrimer/CuS/AA nanocomposites using gamma irradiation cross-linking method with the aid of sonication. They used the prepared materials to evaluate the removal of Isma acid fast yellow G Dye.…”

Study of the effectiveness of the third generation polyamideamine and polypropylene imine dendrimers in removal of reactive blue 19 dye from aqueous solutions

“…The results indicated that adsorption isotherm (26). In another study, nanocomposites including copper sulfide and PAMAM dendrimer were used to remove Isma acid fast yellow G dye, and the results indicated that adsorption obeyed Langmuir model and with pH increase, the rate of adsorption decreased (27).…”

Fabrication and characterization of CMC-based magnetic superabsorbent hydrogel nanocomposites for crystal violet removal

“…The dye‐contaminated water presents a serious environmental problem for both toxicological and esthetical reasons . Thus, in recent years, considerable attention has been paid on the removal of dyes from the contaminated waste water . By now, a wide range of physical and chemical techniques has been applied to control dye contamination such as oxidation, coagulation, biological treatment, and membrane filtration .…”

“…[1,2] Thus, in recent years, considerable attention has been paid on the removal of dyes from the contaminated waste water. [3][4][5] By now, a wide range of physical and chemical techniques has been applied to control dye contamination such as oxidation, [6] coagulation, [7] biological treatment, [7] and membrane filtration. [8] However, the adsorption technique has been found to be superior to other methods because of its simplicity of design, ease of handling, high efficiency, cost-effectiveness, and capability for absorbing a broad range of dyes.…”
