Provided is a method for recovering, by pressure swing adsorption, unreacted olefins from a stream of a chemical reaction process in which an olefin is used as a material, the method enables desorption of gas at a relatively high desorption operation pressure, more preferably at a pressure not lower than the atmospheric pressure, and enables reuse of a separation agent. As the separation agent, a metal complex is used, in which pressure P3 at which a local maximum of dA/dP is obtained during adsorption and pressure P4 at which a local maximum of dA/dP is obtained during desorption are located between an adsorption operation pressure P1 and a desorption operation pressure P2, where dA/dP represents a value obtained by differentiating A by P, assuming that an olefin adsorption amount (A) is a function of an adsorption pressure (P), i.e., A=f(P), on an adsorption isotherm indicating the pressure (P) and the adsorption amount (A).

The invention concerns methods of removing undesirable molecules from the blood or physiologic fluid; said method comprising contacting said blood or physiologic fluid with a sorbent, said sorbent comprising a plurality of solid forms and comprising a cross-linked polymeric material having a plurality of ligands attached to the surface of said cross-linked polymeric material, comprising (i) zwitterionic moieties, (ii) oligo(ethylene glycol) moieties or (iii) mixtures thereof; said contacting comprising said sorbent sorbing a plurality of said undesirable molecules when said sorbent is administered within a patient's body.

A method for pre-analytical treatment of a serum or plasma sample from a patient suspected of suffering from oxidative stress, which includes contacting the sample with one or more microcapsules having a gelled alginate core and a semipermeable coating, where the alginate core includes dispersed receptors against an oxidised human parathyroid hormone (PTH) peptide. The semipermeable membrane can be obtained by layer-by-layer deposition of polycationic and polyanionic macromolecules onto the gelled core, following by hardening, crosslinking and co-acervation of the macroionic phases.
