Title: The Innovative Contributions of Robert F. Landel
Introduction
Robert F. Landel is a notable inventor based in Altadena, California. He has made significant contributions to the field of functional materials, particularly through his innovative work on magnetic microspheres. His research has implications for environmental remediation and materials science.
Latest Patents
Landel holds a patent for "Functional Magnetic Microspheres." This invention involves the formation of functional magnetic particles by dissolving a mucopolysaccharide, such as chitosan, in an acidified aqueous solution containing a mixture of ferrous chloride and ferric chloride. As the pH of the solution is raised, magnetite is formed in situ. The chitosan, acting as a polyelectrolyte, forms micelles that surround the granules at a pH of 8-9. The chitosan precipitates on the granules, resulting in microspheres that contain magnetic granules. These microspheres can effectively bind heavy metal cations, such as lead, copper, and mercury, as well as anions like nitrate, fluoride, phosphate, and borate when added to waste aqueous streams.
