Latest Patents

One of Cullen's latest patents is a membrane-based sorbent for heavy metal sequestration. This innovative process involves making membrane-based sorbents with enhanced binding activity that are particularly useful for capturing heavy metals. The process includes selectively hydrolyzing a polyacetylated membrane to deacetylate a surface layer, exposing free hydroxyl groups. Following this, the hydroxyl groups are oxidized to aldehyde groups. The final step involves attaching a polycarboxylic acid, such as a polyamino acid, polyalkenoic acid, or polypeptide, to the membrane through the aldehyde groups. The hydrolyzing step is preferably completed under alkaline conditions, while the oxidizing step utilizes an aqueous solution of sodium periodate.
