Abstract
A method is provided for the post-treatment of nanoporous celluloses with an eye to scale up to plant operation wherein recycling and recovery of reagents is crucial in the efficient and cost effective operation of a full-scale plant. The instant method includes diminishing the alkali (e.g., sodium hydroxide) concentration of the treatment solution by converting it to a salt (e.g., a sodium salt).
