Patent ID: 8388735

Claim:
An adsorbent media composition comprising: a first media component material selected from the group consisting of polymeric fibers, inorganic fibers, natural fibers, carbon fibers and mixtures thereof; a second media component material having at least 30 weight percent of an adsorbent composition comprising a finished media lithium-exchanged zeolite X (LiX), the finished media LiX having a finished Li content, wherein the finished media LiX is derived from a LiX precursor having a pre-media production Li content; wherein (a) the finished media LiX Li content is reduced relative to the LiX precursor Li content, (b) the finished media LiX Li content is in a range from 96% to 83%, based on the total cation equivalents in the LiX, and (c) the adsorbent media composition is obtained from a slurry mixture comprising water, the pre-media production LiX and the first media component material, wherein (i) the water has a specific conductance in a range from 2.2 .mu.Siemens/cm to 150 .mu.Siemens/cm; (ii) the finished media LiX has a monovalent cation content in a range from 0.05% to 3%, based on the total equivalents of exchangeable cations in the finished media LiX, wherein the monovalent cation is selected from the group consisting of Na, K, Rb, Cs, and combinations thereof; and (iii) the finished media LiX has a divalent cation content in a range from 0.05% to 15%, based on the total cation equivalents in the finished media LiX, wherein the divalent cation is selected from the group consisting of Ca, Mg, Sr, Ba, and combinations thereof.
