Considering
some characteristics of the NFC aerogels adverse to the
cyclic adsorption (e.g., poor mechanical property and
strong shrinkage), the MTCS-treated NFC aerogels were
put into a thin and lightweight nonwoven cloth bag. The
bag was sealed and subjected to the cyclic adsorption tests.
In this way, we need not worry about the shrinkage,
operational and recycling problems. We adopted two
methods to recycle the adsorbent, i.e., squeezing–vacuum
drying for toxic expensive liquids and air drying for cheap
volatile and innoxious liquids.
