Abstract
The present disclosure relates to synthetic membranes for the removal, isolation or purification of substances from a liquid, comprising at least one hydrophobic and at least one hydrophilic polymer, wherein 5-40 wt.-% of particles having an average particles size of between 0.1 and 15 μm are entrapped and wherein the membrane has a wall thickness of below 150 μm. Further disclosed are methods for preparing such membranes in various geometries and their use for the adsorption, isolation and/or purification of substances from a liquid.

-18. (canceled)
A hollow fiber or flat sheet membrane for the removal of substances from a liquid, the membrane comprising i) at least one hydrophobic polymer selected from the group consisting of polysulfones, polyethersulfones, polyarylethersulfones, polyamides and polyacrylonitriles and ii) at least one hydrophilic polymer,
- wherein the membrane comprises particles at 5-40 wt.-%, wherein the particles comprise a) hydrophilic particles, b) hydrophobic particles, or c) a combination of both, and wherein the particles have an average diameter of between 0.1 μm and 15 μm.
A method for adsorption or isolation of compounds from a liquid, said method comprising the step of contacting the liquid comprising the compounds to the membrane of claim 1, wherein the compounds are adsorbed or isolated from the liquid to the membrane.
