Patent
·
OSTI ID:6962948
This patent describes a method of manufacturing a heavy metal-removing mixture of a water-penetrable, insoluble carboxylated cellulose and a plurality of insoluble particles of a heavy metal interactant. It comprises: dispersing solid particles of a heavy metal interactant in a carrier liquid; cross-linking a water-soluble form of a carboxylated cellulose to insolubilize the carboxylated cellulose while in close proximity to the heavy metal interactant particles and entrap some of the heavy metal interactant particles within the insolubilized carboxylated cellulose to form the heavy metal-removing mixture.
