WebBecause the top PA active layer is believed to play a crucial role in the permeaselectivity and antifouling performance, most studies related to GO-modified TFN NF membranes focus on the optimization of the active layer rather than the porous support layer. GO with abundant oxygen-containing functional groups is normally regarded as a kind of WebAn efficient separation of Mg²⁺/Li⁺ with separation factor of 33, accompanied by a permeability as high as 30.6 L/m².h.bar, was obtained. Moreover, the high hydrophilicity of the UiO-66-NH2-based... storm baseball long island
