Abstract

In the present work, the removal of fast sulphon black (FSB) dye from water was executed by using chitin-cl-poly(itaconic acid-co-acrylamide)/zirconium tungstate nanocomposite hydrogel (Ch-cl-poly(IA-co-AAm)-ZrW NCH). The Ch-cl-poly(IA-co-AAm)-ZrW NCH was fabricated proficiently by microwave-induced sol-gel/copolymrization method. The zirconium tungstate (ZrW) photocatalyst was prepared by co-precipitation method using sodium tungstate and zirconium oxychloride in ratio (2:1). The polymeric hydrogel part has been used to support the ZrW, and it acted as an adsorbent for adsorptive removal of FSB dye. The band gap for nanocomposite hydrogel was found about 4.18 eV by using Tauc equation. The Ch-cl-poly(IA-co-AAm)-ZrW NCH was characterized by various techniques as FTIR (Fourier-transform infrared spectroscopy), X-ray diffraction (XRD), transmittance electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS) and scanning electron microscopy (SEM). The adsorptional-photocatalytic remediation experiment of FSB dye was optimized for reaction parameters as FSB dye and Ch-cl-poly(IA-co-AAm)-ZrW NCH concentration, and pH. The maximum percentage removal for FSB dye was observed at 92.66% in 120 min under adsorptional-photocatalysis condition.
