Removal Bismarck Brown G dye from Aqueous Solution Over a Composite of Triazole-Polyvinyl Chloride Polymer and Zinc Oxide

Abstract

The present study involves synthesis a composite of triazole-poly vinyl chloride (PVC) polymer with nano-crystalline zinc oxide to yield triazole-PVC/ZnO. The produced composite was characterized using fouier infrared spectroscopy (FTIR), X-Rays diffraction (XRD) and micro-elemental analysis (CHN). The activity of the produced composite with respect to neat zinc oxide was investigated by following both of adsorption and photocatalytic removal of Bismarck Brown G (BBG)dye from their aqueous solutions. The obtained results in this study showed that triazole-PVC/ZnO was more efficient than neat ZnO on dye removal for both of adsorption and photocatalytic reaction.

“…The synthesized azo compound was also analyzed by 1 S2, and the numbering of the carbons used in the interpretation follows in figure 1. These results confirm the expected structure for [4-(2hydroxy naphthyl)diazenyl] benzoic acid since the spectra are similar to those previously described in studies conducted by Alrazzak, Aowda and Atiyah [50] and George et al [48].…”

“…The FTIR spectrum of [4-(2hydroxy naphthyl)diazenyl] benzoic acid is shown in figure S1 (available online at stacks.iop.org/STMP/ 10/024001/mmedia). This spectrum is very similar to that presented in the study by Alrazzak, Aowda and Atiyah [50], who used this compound azo to synthesize 1,2,4-triazole derivatives.…”

“…The literature reports studies involving azo compounds, which present fluorescent emissions at different wavelengths. These differences are related to the excitation wavelength and the structure of the compound azo [47,50,[57][58][59][60][61].…”

“…Therefore, for increasing the efficiency of solar cell the thin film-based method must be used in which large amount of light is absorbed for a broader range of the solar spectrum [34]. There are different methods of classification of the photovoltaic cells based on their semiconductor materials, morphology and fabrication technique [35,36]. To illustrate solar cells, dye-sensitized solar cells (DSSCs) are discussed due to their simple manufacture and high efficiency, so they have attracted great attention from researchers from around the world [37].…”

“…This type of solar cell is believed to be able to provide alternative energy concept with a more inexpensive cost of the fabrication technology that is simpler than the one made from crystalline silicon before its solar cells. Although until now the energy conversion efficiency of DSSC has been produced by a lower than silicon solar cells, the type of DSSC solar cells is still the potential to produce a much large efficiency in the future [35,36,39]. Many attempts may be made to improve the efficiency of these cells by using the electrodes nanostructured metal oxides [40,41], various dye sensitization [41,42], and an electrolyte containing I -/I3 -redox couples [43,44].…”
