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.
在本工作中，使用甲壳素-聚（衣康酸-co-丙烯酰胺）/钨酸锆纳米复合水凝胶（Ch-cl-poly（IA-co-AAm）-ZrW NCH）从水中去除快速磺基黑（FSB）染料。Ch-cl-poly（IA-co-AAm）-ZrW NCH 通过微波诱导溶胶-凝胶/共聚方法制备。钨酸锆（ZrW）光催化剂通过在 2:1 的比例下使用钨酸钠和氧氯化锆的共沉淀法制备。聚合物水凝胶部分用于支撑 ZrW，并作为吸附剂用于吸附去除 FSB 染料。通过 Tauc 方程发现纳米复合水凝胶的带隙约为 4.18 eV。Ch-cl-poly（IA-co-AAm）-ZrW NCH 通过各种技术进行了表征，如傅里叶变换红外光谱（FTIR）、X 射线衍射（XRD）、透射电子显微镜（TEM）、能谱（EDS）和扫描电子显微镜（SEM）。FSB 染料的吸附-光催化修复实验对反应参数进行了优化，如 FSB 染料和 Ch-cl-poly（IA-co-AAm）-ZrW NCH 浓度和 pH 值。在吸附-光催化条件下，FSB 染料的最大去除率在 120 分钟内达到 92.66%。
