Abstract

Harmful heavy metals have a significant effect on the toxicity of wastewater due to their non-biodegradability; hence, they will harm living things. Graphene oxide has been studied in recent research to remove these heavy metals. This study was carried out to determine the characterization of graphene oxide-based hyperbranched polymers (GO-MHBP) and their batch experiments on removing heavy metals (Cr³⁺ and Hg²⁺). The surface of the graphene oxide particles was modified by 3-(aminopropyl) triethoxysilane, and then hyperbranched polymers were fabricated by incorporating 3,5-diaminobenzoic acid and maleic anhydride. The synthesized polymers were characterized physically and morphologically using FT-IR, FE-SEM, EDX, and TGA techniques. Moreover, they were assessed in terms of adsorption capacity to remove pollutants of Cr³⁺ and Hg²⁺. To that end, the effect of pH, adsorbent amount, contact time, and initial concentrations of metal ions was evaluated. Furthermore, the adsorption kinetics and isothermal behavior were investigated for the adsorption efficiency of GO-MHBP nanocomposite. The adsorption process was consistent with the second-order kinetic model and the Langmuir isotherm model. Eventually, the GO-MHBP could serve as promising adsorbents for potential application in the removal of Cr³⁺ and Hg²⁺ from wastewater.

Graphical abstract

Graphene oxide-based hyperbranched polymers provided an effective adsorbent system for heavy metal removal. These nanocomposites are significant for the remediation and removal of Cr³⁺ and Hg²⁺ ions from wastewater due to their simple synthesis method and low cost

基于纳米颗粒的超支化聚合物的合成与表征，用于去除水中的污染物

有害重金属具有不可生物降解性，对废水的毒性有很大影响，因此会对生物造成危害。最近的研究发现，氧化石墨烯可以去除这些重金属。本研究旨在确定基于氧化石墨烯的超支化聚合物（GO-MHBP）的特性及其去除重金属（Cr3+ 和 Hg2+）的批量实验。用 3-（氨基丙基）三乙氧基硅烷修饰氧化石墨烯颗粒表面，然后加入 3,5-二氨基苯甲酸和马来酸酐制备超支化聚合物。利用傅立叶变换红外光谱、FE-SEM、EDX 和 TGA 技术对合成聚合物进行了物理和形态学表征。此外，还对它们去除 Cr3+ 和 Hg2+ 污染物的吸附能力进行了评估。为此，还评估了 pH 值、吸附剂用量、接触时间和金属离子初始浓度的影响。此外，还研究了 GO-MHBP 纳米复合材料的吸附动力学和等温行为，以了解其吸附效率。吸附过程符合二阶动力学模型和 Langmuir 等温线模型。最终，GO-MHBP 纳米复合材料有望作为吸附剂用于去除废水中的 Cr3+ 和 Hg2+。由于其合成方法简单、成本低廉，这些纳米复合材料对于修复和去除废水中的 Cr3+ 和 Hg2+ 离子具有重要意义。
