The functionalization of lignin derivatives for ion removals is a promising method to expedite their use in treating industrial wastewater. In this work, kraft lignin (KL) was polymerized with [2-(methacryloyloxy)ethyl]trimethylammonium methyl sulfate (METAM) or acrylic acid (AA) in an acidic aqueous suspension system to produce cationic and anionic water-soluble lignin polymers with high molecular weights. Then, the interaction of soluble ions and KL-METAM and KL-AA was investigated using a Quartz crystal microbalance (QCM) and a vertical scan analyzer (VSA). The QCM, X-ray photoelectron spectroscopy (XPS) and contact angle measurement results showed that the adsorption efficiency of KL-AA was better than KL-METAM for ions due to the stronger electrostatic interaction, cationic π-interaction, and chelation between ions and KL-AA. Based on adsorption, sedimentation, and aggregate size analyses, the dual polymer systems of KL-AA/KL-METAM were more effective than KL-METAM/KL-AA in removing ions. Among Zn²⁺, Cu²⁺, and K⁺; Zn²⁺ interacted more effectively with polymers in all scenarios because it has higher reactivity for interacting with other elements. As the efficiency of ion removals was more remarkable than past reported findings, the system of KL-AA/KL-METAM may be a promising alternative for the removal of dissolved ions from solutions.

木质素衍生物用于离子去除的功能化是加快其在工业废水处理中的应用的有前途的方法。在这项工作中，在酸性水悬浮体系中，将牛皮纸木质素（KL）与[2-（甲基丙烯酰氧基）乙基]三甲基硫酸铵（METAM）或丙烯酸（AA）聚合，以生产阳离子型和阴离子型水溶性木质素聚合物分子量。然后，使用石英晶体微量天平（QCM）和垂直扫描分析仪（VSA）研究了可溶性离子与KL-METAM和KL-AA的相互作用。QCM，X射线光电子能谱（XPS）和接触角测量结果表明，由于较强的静电相互作用，阳离子π相互作用以及离子与金属之间的螯合作用，KL-AA对离子的吸附效率优于KL-METAM。 KL-AA。基于吸附，沉降和聚集体尺寸分析，KL-AA / KL-METAM的双聚合物系统在去除离子方面比KL-METAM / KL-AA更有效。锌之中²⁺，Cu ²⁺和K ⁺ ; Zn ²⁺在所有情况下均与聚合物更有效地相互作用，因为它与其他元素的相互作用具有更高的反应性。由于离子去除效率比过去报道的结果更为显着，因此KL-AA / KL-METAM系统可能是从溶液中去除溶解离子的有前途的替代方法。
