Three-dimensional-printed calcium alginate/graphene oxide porous adsorbent with super-high lead ion adsorption ability in aqueous solution

Separation and Purification Technology 2023 Volume 326, Article 124757

Using three-dimensional (3D) printing technology, a 3D calcium alginate/graphene oxide (3D CA/GO) adsorbent, with a hierarchical macroporous structure, was successfully constructed. Owing to the optimized construction process, the 3D CA/GO showed an enhanced adsorption capacity (490.2 mg/g at pH = 3.0) for lead (Pb(II)) in aqueous solution, which was two times higher than reported in the literature). Meanwhile, the selective adsorption ratio of 3D CA/GO for Pb(II) reached 99.8% when positive ions occurred. In addition, after eight adsorption–desorption cycles, the adsorption capacity did not experience a significant decrease and the structure remained stable. Meanwhile, the adsorbed Pb(II) could be eluted…
