The design of efficient adsorbent with abundant binding sites for heavy metal ions is crucial for developing innovative materials that will remove pollutant metal ions. The high uptake capacity, kinetics, and affinity towards the toxic metals are the key requirements that the materials under invesigation should accomplish. Here we report the synthesis of iminodiacetic acid-functionalized hypercrosslinked polymer (IDA-HCP) for purification of water polluted by toxic metal ions via coordination of carboxylate and amino active sites on the surface of porous polymer. The obtained porous polymer is stable under harsh conditions and the structural features on the polymer work together to help the removal of Pb(II) with 1138 mg g^–1 uptake capacity. In the meanwhile, the IDA-HCP reveals reuseability and very promising capture efficiency not only for Pb²⁺, but also for Hg²⁺ and Cd²⁺ from a mixture of Pb²⁺, Hg²⁺, Cd²⁺, Co²⁺, Fe³⁺, Zn²⁺, Mg²⁺, and Na⁺ metal ions. This result gives us confidence that the polymer material can solve the pollution problem caused by various metal ions.

具有丰富的重金属离子结合位点的高效吸附剂的设计对于开发可去除污染物金属离子的创新材料至关重要。对有毒金属的高吸收能力，动力学和亲合力是所研究材料应满足的关键要求。在这里，我们报告了亚氨基二乙酸功能化的超交联聚合物（IDA-HCP）的合成，用于通过多孔聚合物表面上的羧酸盐和氨基活性位点的配伍来纯化被有毒金属离子污染的水。所获得的多孔聚合物在苛刻的条件下是稳定的，并且聚合物上的结构特征共同起作用，有助于以1138 mg g ^–1的吸收能力去除Pb（II）。同时，IDA-HCP揭示了Pb 2 ⁺，Hg 2 ⁺，Cd 2 ⁺，Co 2 ⁺，Fe ³⁺，Zn ²的混合物不仅对Pb ²⁺，而且对Hg ²⁺和Cd ^2+的重用性和非常有希望的捕获效率⁺，Mg ²⁺和Na ⁺金属离子。该结果使我们确信该聚合物材料可以解决各种金属离子引起的污染问题。
