Abstract:Hydrogels possess a strong water
absorption capability and can
release absorbed water in response to physical or chemical stimuli,
making them promising materials for water recycling. To explore the
concept of using hydrogels to recover water from wastewater, we synthesized
and utilized poly(acrylic acid-co-acrylamide) (PAAM)
hydrogels to extract water from solutions containing various organic
pollutants and salt concentrations. The swelling ratio of PAAM hydrogels
reached up to 510 g/g with a water recovery … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
