文章采用反相悬浮聚合方法，通过缩合聚合反应制备了带有邻羟基基团的硼螯合树脂。通过控制投料方式和升温方式，对分散介质、反应溶剂种类及用量、反应温度和时间等参数进行调整，优化了树脂的制备工艺；考察了吸附溶液pH值、硼酸初始浓度对树脂吸附性能的影响。结果表明，在最优条件下，树脂对硼酸表现出84.5 mg/g的高吸附量，优于商品化Amberlite IRA-743树脂；在硼硅混合体系中，该树脂表现出优异的吸附选择性，硼选择性系数为1384。
Abstract：In this study, based on condensation polymerization, boron chelate resin with o-hydroxyl group was prepared by reversed-phase suspension polymerization. The structure of the resin was optimized by controlling the feeding mode and heating mode, and adjusting the dispersing medium, the type and amount of reaction solvent, reaction temperature and time. The effects of pH and initial concentration of adsorption solution on boron adsorption performance were investigated. Under optimal conditions, the resin showed a high adsorption capacity of 84.5 mg/g for boric acid, which was better than commercial Amberlite IRA-743 resin. In the boron-silicon mixed system, the resin showed excellent boron selectivity and boron adsorption performance, with a boron selectivity coefficient of 1384.
