摘要： A water purification device is provided in the form of a hydrogel matrix containing immobilized nanoparticles that are directly synthesized in-situ in the hydrogel matrix. The hydrogel matrix is temperature sensitive, such that swelling draws in pollutants that are captured by the nanoparticles, while deswelling releases purified water. A related method of decontaminating the water supply contaminated with a target pollutant is also disclosed.

摘要： A process is provided for making membrane-based sorbents with enhanced binding activity that are particularly useful for heavy metal sequestration. The process includes the step of selectively hydrolyzing a polyacetylated membrane in order to deacetylated a surface layer of said membrane including the pore surfaces and expose free hydroxyl groups. This is followed by the oxidizing of the hydroxyl groups to aldehyde groups. This is then followed by the attaching of a polycarboxylic acid such as a polyamino acid, polyalkenoic acid or polypeptide to the membrane through the aldehyde groups. Preferably, the hydrolyzing step is completed under alkaline conditions and the oxidizing step is completed using an aqueous solution of sodium periodate.
