Abstract (en)
[origin: US5846297A] PCT No. PCT/EP95/04036 Sec. 371 Date Jun. 30, 1997 Sec. 102(e) Date Jun. 30, 1997 PCT Filed Oct. 13, 1995 PCT Pub. No. WO96/12551 PCT Pub. Date May 2, 1996Polyarylene ethers are employed as filter material for removing NO2 from gases and liquids. In the presence of an oxidizing agent having a redox potential of at least 0.96 V SHE, NO can also be removed. The filter material is used to produce NO2-free gases, for example in the medical sector.
