Graphene oxide/locust bean gum (GO/LBG) aerogels, synthesized in an ice crystal template without using any chemical modifiers, were used for the treatment of water pollution. Various characterization results showed that GO/LBG aerogel exhibited a network-like three-dimensional (3D) structure with large specific surface area. The adsorption data revealed that GO/LBG aerogels with GO/LBG mass ratio of 1:4 (GO/LBG-1 aerogels) exhibited more prominent adsorption properties for Rhodamine-B (RhB, 514.5 mgg) than Indigo Carmine (IC, 134.6 mgg). Simultaneously, GO/LBG-1 aerogels could selectively remove RhB from a binary mixed solution of RhB-IC dyes. Furthermore, GO/LBG-1 aerogels also displayed excellent reusability and could still reach 92.4 % after ten cycles. Based on the above results, GO/LBG-1 aerogel could be considered as an ideal adsorbent with potential application value for removing water-soluble RhB from wastewater.
氧化石墨烯/槐豆胶（GO/LBG）气凝胶是在冰晶模板中合成的，无需使用任何化学改性剂，可用于处理水污染。各种表征结果表明，GO/LBG 气凝胶呈现出具有大比表面积的网络状三维（3D）结构。吸附数据表明，GO/LBG 质量比为 1:4 的 GO/LBG-1 气凝胶（GO/LBG-1 aerogels）对罗丹明 B（RhB，514.5 mgg）的吸附性能比靛蓝胭脂红（IC，134.6 mgg）更为突出。同时，GO/LBG-1 气凝胶可从 RhB-IC 染料的二元混合溶液中选择性地去除 RhB。此外，GO/LBG-1 气凝胶还表现出优异的可重复使用性，在十次循环后仍可达到 92.4%。基于以上结果，GO/LBG-1 气凝胶可用作理想的吸附剂，有望用于从废水中去除水溶性 RhB。
