摘要

采用离子交联法制备海藻酸钠-镧(SA/Lan)水凝胶球，以去除水溶液中的刚果红(CR)。通过批量实验对其吸附性能进行了评价。实验结果表明，当La3+的质量浓度为1%，用量为2 g·L−1,CR的初始浓度为30 mg·L−1，吸附时间为60 min，反应温度为25℃时，SA/Lan对CR的吸附量最高。吸附量为10.81 mg·g−1。吸附过程符合Langmuir模型和拟二阶模型。

Preparation and Adsorption Performance on Congo Red of Sodium Alginate-Lanthanum Hydrogel Spheres

Sodium alginate-lanthanum (SA/Lan) hydrogel spheres were prepared by ion cross-linking method to remove Congo Red (CR) in an aqueous solution. The adsorption performance was assessed through batch experiments. The experiment revealed that the highest adsorption capacity of SA/Lan for CR was achieved when the mass concentration of La³⁺ was 1%, the dosage was 2 g·L⁻¹, the initial concentration of CR was 30 mg·L⁻¹, the adsorption time was 60 min, and the reaction temperature was 25°C. The adsorption capacity of 10.81 mg·g⁻¹ was the corresponding figure. The adsorption process was consistent with the Langmuir and pseudosecond-order models.
