Title: Innovations of James K Smith
Introduction
James K Smith is a notable inventor based in Baton Rouge, LA (US). He has made significant contributions to the field of water filtration and polymer membranes. With a total of 4 patents, his work has had a considerable impact on environmental technology.
Latest Patents
One of his latest patents is a water filtration medium and method of use. This invention is capable of removing heavy metals from groundwater and surface supplies. The medium comprises a gamma form of manganese dioxide that has been comminuted and divided into fractions according to mesh size. These fractions include sizes of 10 to 40 mesh, 40 to 100 mesh, and 100 to 325 mesh. The particles in a given mesh size are treated with a reducing agent such as ferrous sulfate and then washed with water to remove iron precipitates and fines. The washed particles are treated with a solution of sodium hydrosulfite and sodium bisulfite. Afterward, the treated particles are neutralized with sodium hydroxide to remove remaining acidity. The neutralized particles are washed again to remove spent chemicals and undissolved metals. Finally, the particles are dried prior to use as a filtration medium. Another significant patent involves asymmetric permselective polyacetylene membranes. This invention provides asymmetric polyacetylene polymer membranes that have both improved selectivity and improved flux. The process includes forming a solution containing from about 1 to about 5% by weight of a polyacetylene polymer in a suitable solvent, forming the solution into a thin film, and quenching the film in an aqueous bath with a surfactant.
