    摘要: Abstract A solid polymer electrolyte composition is made by hydrolyzing cellulose in a dissolution media to form a first mixture; then combining said first mixture with an antisolvent to form a precipitate; and then (in any order) separating said precipitate from excess antisolvent and excess dissolution media; optionally adjusting or neutralizing the pH of said precipitate; optionally washing said precipitate with water; combining said precipitate with an electrolyte salt and a hydrophilic polymer to form a wet polymer electrolyte composition; and then drying said wet polymer electrolyte composition to produce a solid polymer electrolyte composition. Solid polymer electrolyte compositions produced by the process, along with films formed therefrom and devices containing the same, are also described.

    摘要: Improved systems and methods for removing the load of perchlorate and other oxyanions off of ion exchange resins through bioregeneration are disclosed. The improved systems and methods rely upon direct contact between the resin and a liquid product containing enrichment cultures of or pure strains of perchlorate-destroying microorganisms. Controlled temperatures also lead to improvements as do upflow conditions leading to bed expansion. These methods can be incorporated into methods for removing perchlorate from aqueous streams.
