Pore Size Adjustment of Sodium Alginate-Based Composite Aerogel Spheres by Zirconia for Efficient Selective Removal of Cu(Ii)

Recent advances in the environmental application of graphene-based composites

“…149 3.2.4 Other heavy metals. Apart from the above heavy metals, there are many research studies concerning the removal of other heavy metals (e.g., Hg(II), 151,153 Ni(II), 150,154 Cu(II) [155][156][157] ) on graphene-based composites in the recent years. The adsorption capacity of GO towards various metal ions followed the order of Cu(II) > Ni(II) > Co(II) with excellent regeneration capacity (Fig.…”

“…154 The high adsorption capacity of Cu(II) (132.57 mg g −1 ) on GO-zirconium oxide/sodium alginate was due to the strong electrostatic force, ion exchange and complexation. 155 Chang et al investigated the real industrial wastewater treatment of Cu(II) (>98%) using bentonite/GO composites. 158 Briefly, two samples of real Cu-bearing industrial wastewater were pre-cleaned with HNO 3 and then rinsed thoroughly with DI water.…”
