摘　　要：染料和低共熔溶剂的广泛使用会产生大量的废液,同时低共熔溶剂在回收锂离子电池正极材料过程中也会产生含钴、锂离子的浸出液。本文发现羟基功能化二维共轭微孔聚合物(Two-dimensional Conjugated Microporous Polymer,CMP)能高效回收染料废液、低共熔溶剂及锂电回收浸出液。羟基功能化CMP对乙二醇:抗坏血酸(10:1)DESs含钴酸锂的浸出液吸附效率高达1031.5%。The widespread application of dye and deep eutectic solvents(DESs)would produce industrial harmful wastewater.Meanwhile,waste leachate is released from deep eutectic solvent after recycling lithium-ion batteries.Here,we use hydroxyl functionalized two-dimensional con-jugated microporous polymer(CMP)to recover dye wastewater,DESs and leachate after leaching lithium-ion batteries cathode by DESs.It pro-vides a simple and efficient route for the treatment of waste liquid.The adsorption efficiency of hydroxyl functionalized CMP for DESs ethylene gly-col:ascorbic acid(10:1)containing lithium cobaltate leaching solution could reach as high as 1031.5%.
