通过静态和动态实验，研究了超交联树脂（HPCR）对酸性黑1 （AB）和Cu （II）的协同去除效果，结果表明，在单一、二元和生理盐水体系中，HPCR对酸性黑1 （AB）和Cu （II）的协同去除效果远远优于商业吸附剂。AB的共存明显增强了Cu （II）的吸附，是单独体系的14倍左右，而AB的吸附受Cu （II）存在的影响很小。其中，Cu （II）和AB的回收率分别超过99.9%和93.4%，首次报道了共吸附物的顺序回收。此外，离子强度对HPCR的性能有正向影响。此外，通过预加载、动力学测试和水固相表征验证，络合物吸附和表面络合物相互作用都是增强Cu （II）吸附的潜在机制，并且后者更为重要。对于表面络合物相互作用，固相AB的磺酸基和氨基等新的活性位点可能参与了Cu （II）摄取的加强。这些在协同去除和顺序回收方面的发展趋势以及潜在的机制探讨了HPCR在综合有效处理共存有毒污染物中的应用。
The synergic removal of acid black 1 (AB) and Cu (II) onto hyper-crosslinked resin (HPCR) was deeply investigated with static and dynamic procedures in sole, binary and saline systems, which was proved to be far superior to those on commercial adsorbents. The coexistence of AB markedly enhanced the adsorption of Cu (II), being around 14 times of that in sole system, while AB adsorption was only a little affected by the presence of Cu (II). Specifically, the sequential recovery of the co-adsorbates was firstly reported with the recovery ratio of more than 99.9% and 93.4% for Cu (II) and AB individually. Additionally, ionic strength exerted positive influence on the properties of HPCR. Furthermore, upon the certification by preloading, kinetic tests and aqueous/solid-phase characterizations, complex-adsorption and surface complex-interaction were both demonstrated as potential mechanisms for the enhancement of Cu (II) adsorption, and the latter was more predominant. For surface complex-interaction, such new active sites as sulfonic and amino groups of AB in solid-phase likely participated in strengthening Cu (II) uptake. These promising trends in the synergic removal and sequential recovery as well as the potential mechanisms explored the application of HPCR, in integrative and efficient treatment of coexistent toxic pollutants.
