Wael I. Mortada has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Dispersive liquid-liquid microextraction of copper and zinc ions from real samples using selective organoselenium-based ligands
    Patent number: 11981627
    Abstract: Novel organoselenium selective ligands are presented and designed to determine metal ions in a sample. These ligands are used as complexing agents in a dispersive liquid-liquid microextraction procedure of copper and zinc ions. The procedure has a shortened extraction time, minimal organic solvent types, and lower amounts of solvents, as well as easy operation and high enrichment efficiency.
    Type: Grant
    Filed: September 12, 2023
    Date of Patent: May 14, 2024
    Assignee: KING FAISAL UNIVERSITY
    Inventors: Hany Mohamed Abd El-Lateef Ahmed, Saadeldin Elsayed Ibrahim Shabaan, Mai Mustafa Khalaf Ali, Mohamed Gouda, Wael I. Mortada
