Disclosed is a system and method of treatment which provides a direct response to the treatment of pneumonia as related to infections using a powder comprising a polyiodide resin with broad spectrum bactericidal, fungicidal and virucidal properties. When the powder is applied directly to the lungs of a mammal an immediate contact kill of protozoa, bacteria, fungi and viruses that cause respiratory tract infections affecting the lungs of a mammal takes place. Also disclosed is an application of the polyiodide resin powder for use with personal protective equipment (PPE) including but not limited to face masks, face shields, and respirators.

A composite extractant-enhanced polymer resin comprising an extractant and a polymer resin for direct extraction of valuable metals such as rare earth metals, and more specifically, scandium, front an acid-leaching slurry and/or acid-leaching solution in which ferric ions are not required to be reduced into ferrous ions. The extractant may be cationic, non-ionic, or anionic. More specifically, the extractant di(2-ethylhexyl)phosphoric acid may be used. The polymer resin may be non-functional or have functional groups of sulfonic acid, carboxylic acid, iminodiacetic acid, phosphoric acid, or amines. The composite extractant-enhanced polymer resin may be used for extraction of ran earth metals from acid-leaching slurries or solutions.
