Title: Lester B. Gress: Innovator in Metal Contaminant Removal
Introduction
Lester B. Gress is a notable inventor based in Brecksville, OH (US). He has made significant contributions to the field of environmental technology, particularly in the removal of metal contaminants from aqueous solutions. With a total of 2 patents, Gress has developed innovative solutions that address critical environmental challenges.
Latest Patents
Gress's latest patents focus on the creation of beads designed to remove dissolved metal contaminants. The first patent describes a bead that consists primarily of peat moss immobilized by a crosslinked neutralized poly(carboxylic acid) binder, sodium silicate binder, or polysulfone binder. This bead is effective in removing metal contaminants from dilute aqueous solutions. The method of making these metal-ion-sorbing beads involves combining peat moss or other nonliving biomass with a binder solution, forming wet beads, and subsequently heating and drying them. The preferred binder solution includes poly(acrylic acid) and glycerol dissolved in water, with the wet beads being crosslinked through radio frequency heating.
The second patent also focuses on a bead made from peat moss or other nonliving biomass, immobilized by sodium silicate or polysulfone binder. This bead serves a similar purpose in removing metal contaminants from dilute aqueous solutions. The method for creating these beads involves mixing peat moss or biomass with a liquid binder, forming wet beads, and drying them. The liquid binder is typically sodium silicate dissolved in water or polysulfone dissolved in methylene chloride.
