Abstract

Textile wastewater containing heavy metal ions has become a severe environmental problem worldwide. The combined uptake of heavy metals and dyes from wastewater discharged by different sectors is a challenging concept. This study explores the use of hybrid adsorbent based on magnetic chitosan (MC) and magnetic poly glycidyl methacrylate (Mp(GMA)) in adsorption technology, for simultaneous removal of Eriochrome Black T (EBT) dye and chromate anions from their binary aqueous solution. The adsorbent material was functionalized by loading diethylenetriamine (DETA) or dithizone to improve their adsorption capacity (R-DETA or R-Dithizone). The physicochemical characteristics of the materials have been characterized by a wide variety of analytical techniques. Pseudo-second order kinetic model and Langmuir adsorption isotherms were the best-fit models in the binary adsorption system. The co-presence of these anions in the binary solution increases the adsorption capacity of chromate and diminishes the EBT adsorption capacity of the investigated adsorbents (R-DETA and R-Dithizone). The adsorption capacity at monolayer saturation capacities (Langmuir) of R-DETA in binary system were 0.782 and 4.11 mmol g⁻¹ towards EBT and chromate anions respectively, while R-Dithizone adsorbent recorded lower monolayer sorption capacity for EBT (0.490 mmol g⁻¹ ) and higher sorption capacity for chromate 5.93 mmol Cr(VI) g⁻¹ in the binary solution. The effects of competitive anions Cl⁻, NO₃⁻, SO₄²⁻, and MnO₄⁻ on the adsorption of EBT and chromate anions in their binary mixture were examined. The good sorption ability of EBT and Cr(VI) anions against ionic interference supported their use in wastewater treatment applications. NaOH (0.5 M) proved the most effective for desorption from their binary mixture.

利用功能化杂化磁性聚合物同时去除水溶液中的铬黑 T 和铬酸根阴离子

含有重金属离子的纺织废水已成为全球严重的环境问题。从不同行业排放的废水中综合吸收重金属和染料是一个具有挑战性的概念。本研究探讨了在吸附技术中使用基于磁性壳聚糖（MC）和磁性聚缩水甘油醚甲基丙烯酸酯（Mp(GMA)）的混合吸附剂，以同时去除二元水溶液中的 Eriochrome Black T（EBT）染料和铬酸盐阴离子。吸附材料通过添加二乙烯三胺（DETA）或双硫酮（R-DETA 或 R-Dithizone）进行功能化，以提高其吸附能力。这些材料的理化特性已通过多种分析技术进行了表征。在二元吸附体系中，伪二阶动力学模型和朗缪尔吸附等温线是最适合的模型。这些阴离子在二元溶液中的共存增加了铬酸盐的吸附能力，降低了所研究吸附剂（R-DETA 和 R-二硫酮）的 EBT 吸附能力。R-DETA 在二元体系中对 EBT 和铬酸根阴离子的单层饱和吸附容量（Langmuir）分别为 0.782 和 4.11 mmol g-1，而 R-Dithizone 吸附剂在二元溶液中对 EBT 的单层吸附容量较低（0.490 mmol g-1），对铬酸根的吸附容量较高，为 5.93 mmol Cr(VI) g-1。研究了竞争性阴离子 Cl-、NO3-、SO42- 和 MnO4- 对 EBT 和铬酸盐阴离子二元混合物吸附的影响。EBT 和六价铬阴离子对离子干扰的良好吸附能力支持了它们在废水处理中的应用。事实证明，NaOH（0.5 M）对它们二元混合物的解吸最为有效。

期刊介绍： The Journal of Polymers and the Environment fills the need for an international forum in this diverse and rapidly expanding field. The journal serves a crucial role for the publication of information from a wide range of disciplines and is a central outlet for the publication of high-quality peer-reviewed original papers, review articles and short communications. The journal is intentionally interdisciplinary in regard to contributions and covers the following subjects - polymers, environmentally degradable polymers, and degradation pathways: biological, photochemical, oxidative and hydrolytic; new environmental materials: derived by chemical and biosynthetic routes; environmental blends and composites; developments in processing and reactive processing of environmental polymers; characterization of environmental materials: mechanical, physical, thermal, rheological, morphological, and others; recyclable polymers and plastics recycling environmental testing: in-laboratory simulations, outdoor exposures, and standardization of methodologies; environmental fate: end products and intermediates of biodegradation; microbiology and enzymology of polymer biodegradation; solid-waste management and public legislation specific to environmental polymers; and other related topics.
