摘要

在这项研究中,我们合成了珠状白炭黑,并评估了其吸附罗丹明 B 染料的性能。BS 吸附剂是利用二氧化硅粉末和环保生物聚合物海藻酸钠通过蛋盒连接法合成的。研究发现,在制造过程中通过调整二氧化硅与海藻酸钠的摩尔比,可以控制比表面积和孔径。由于在热处理过程中有效地去除了海藻酸,BS-2.5 样品表现出最高的比表面积和吸附能力。随着孔径的减小,BS 材料的假一阶吸附动力学常数和有效扩散率降低,而吸附容量增加。利用 Langmuir 和 Freundlich 等温线建立了罗丹明 B 的吸附行为模型。根据这些模型的计算结果,比表面积最大的 BS-2.5 样品表现最佳。此外,在连续流系统实验中,使用 BS 能产生干净的水,而使用硅粉的色谱柱则会因严重的压力下降而导致结构损坏和染料泄漏。

Synthesis and Property Control of Bead-Shaped Silica Adsorbents for Rhodamine B Dye Adsorption

In this study, we synthesized Bead-Shaped Silica and evaluated its performance in adsorbing the dye Rhodamine B. The Bead-Shaped Silica (BS) was synthesized without the use of harmful substances. The BS Adsorbent was synthesized using silica powder and the eco-friendly biopolymer sodium alginate through the Egg box junction method. It was found that by adjusting the molar ratio of silica to alginate during the manufacturing process, the specific surface area and pore size could be controlled. The BS-2.5 sample exhibited the highest surface area and adsorption capacity due to the effective removal of alginate during heat treatment. The pseudo-first-order adsorption kinetic constants and effective diffusivity of the BS material decreased with decreasing pore size, while the adsorption capacity increased. The adsorption behavior of Rhodamine B was modeled using Langmuir and Freundlich isotherms. Based on calculations using these models, the BS-2.5 sample, which had the largest surface area, showed the best performance. Additionally, in continuous flow system experiments, the use of BS resulted in clean water production, whereas columns with silica powder experienced structural damage and dye leakage due to severe pressure drops.

期刊介绍: The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
