Tóm tắt

An efficient adsorbent for Ga(III) recovery was developed by applying the geochemical principles of Ga mineralization, using Al-rich clay minerals with a natural affinity for Ga as the raw material. Sodium alginate (SA) facilitated the cross-linked assembly of montmorillonite nanosheets (MMTNS), forming a three-dimensional structured hydrogel. This was achieved through electrostatic interactions between -OH groups on the edges of MMTNS and -COO
