Abstract

Conventional powdered adsorbents often suffer from aggregation, difficult recovery, and poor reusability, limiting their practical application in wastewater treatment. In this study, a 3D-printed zeolite/MgAl layered double oxides (MgAl LDO) composite (3D-Ze/LDO) was successfully developed to overcome these challenges while offering dual-functional dye removal capabilities. Materials characterization, including scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier-transform infrared (FTIR) spectroscopy, confirmed the successful formation of zeolite - LDO composite in the 3D-printed structure. Adsorption experiments demonstrated that both 3D-Ze and 3D-Ze/LDO achieved high methylene blue (MB) removal at approximately 98 %, while the incorporation of LDO significantly enhanced congo red (CR) removal from 67 % (3D-Ze) to 79 % (3D-Ze/LDO) due to the introduction of anion-exchange sites. Kinetic studies revealed that PSO kinetics best described both MB and CR adsorption, indicating a chemisorption-dominated process. Additionally, 3D-Ze/LDO exhibited good reusability over four adsorption cycles, demonstrating its stability and potential for practical applications. These findings highlighted the advantages of 3D-printed adsorbents in addressing the limitations of powdered materials while leveraging the dual-functionality of zeolite and LDO for efficient cationic and anionic dye removal.

3d打印沸石- mgal层状双氧化物（3D-Ze/LDO）作为可重复使用的吸附剂，具有双重功能，可有效去除水中的阴离子和阳离子污染物

传统的粉状吸附剂存在结块、回收困难、可重复使用性差等问题，限制了其在废水处理中的实际应用。在这项研究中，成功开发了一种3d打印沸石/MgAl层状双氧化物（MgAl LDO）复合材料（3D-Ze/LDO），以克服这些挑战，同时提供双功能染料去除能力。材料表征，包括扫描电镜（SEM）、x射线衍射（XRD）和傅里叶变换红外（FTIR）光谱，证实了在3d打印结构中成功形成沸石- LDO复合材料。吸附实验表明，3D-Ze和3D-Ze/LDO均能达到98%的亚甲基蓝（MB）去除率，而由于引入阴离子交换位点，LDO的加入显著提高了刚果红（CR）的去除率，从67% （3D-Ze）提高到79% （3D-Ze/LDO）。动力学研究表明，PSO动力学最能描述MB和CR的吸附，表明这是一个化学吸附为主的过程。此外，3D-Ze/LDO在四个吸附循环中表现出良好的可重复使用性，证明了其稳定性和实际应用潜力。这些发现突出了3d打印吸附剂在解决粉状材料局限性方面的优势，同时利用沸石和LDO的双重功能高效去除阳离子和阴离子染料。
