The support membrane of the inoganic solids porous membrane supported by inoganic solids porous support is included, wherein the support membrane is included includes M with CN parts n+ Cation and Alk + y [M'(CN) m ] x‑ The nano particle of the metal coordinating polymer of anion, wherein M are transition metal, and n is 2 or 3；Wherein Alk is alkali metal, and y is that 0,1 or 2, M' is transition metal, and x is 3 or 4, and m is 6 or 8；The M of the coordination polymer n+ Cation is connected by organic metal key or coordinate bond with the organic group of organic graft, organic graft on the surface of filter membrane, the filter membrane hole inside, and optionally the supporting mass hole inside carry out chemical bond.Method for preparing the support membrane.For making the method that at least one metal cation and solid particle are separated from the liquid medium comprising them using the support membrane. |
