Title: Craig A. Bowe and His Patent for Metal Extraction

Introduction

Craig A. Bowe is an inventor associated with Tampa, Florida, and the University of South Florida. His patent work addresses a method for attaching metal-binding molecules to silica gel, creating a material that can remove heavy metal ions from water.

Latest Patents

Bowe’s listed patent is “Extraction of Metals by Mercaptans Attached to Silica Gel by Azeotropic Distillation.” The invention describes attaching a ligand containing a hydroxyl group and coordinating atoms to silica gel. The process combines silica gel, the ligand, and concentrated sulfuric acid in toluene, then heats the mixture while water is removed through azeotropic distillation. After the toluene is filtered and recycled, the supported ligand is dried under reduced pressure.

The resulting composite can be used in batch or column methods to remove heavy metal ions from aqueous solutions. Bowe is credited with 1 patent.

Career Highlights

Bowe’s documented patent highlights his work on functionalized silica materials and their potential use in water treatment. The invention’s approach binds a metal-coordinating ligand to a solid support, allowing the material to interact with heavy metal ions in solution. His listed institutional affiliation is the University of South Florida.
