Metal Scavengers Based on Alkane Diamine and Alkane Dithiol-Modified Poly-1,4-Dihydropyridazines and Polypyridazines.
ua17-128 – Title: Metal Scavengers Based on Alkane Diamine and Alkane Dithiol-Modified Poly-1,4-Dihydropyridazines and Polypyridazines Invention: The invention is a new class of metal ion scavengers that can bind to transition, lanthanide, and actinide metals from water or organic solvents. This new class is 3,6-diaminoalkane, dithiolakane substituted 1,4-dyhidropyridazine, or 3,6-dipyri-2-yl-4,5... Read More
ua17-086 – Invention: The proposed technology is a pretreatment step that will aid in the degradation of aromatic compounds with nitro substituents (explosives, TNT, plasticizers, dinitroluene). It involves the injection of an inexpensive reducing agent that results in reduction of one or more of the contaminant’s nitro groups to amines rendering the contaminant more susceptible to conventional...

ua16-051 – Title: Pretreatment for In Situ Chemical Oxidation Invention: UA Researchers have tested and proposed a pretreatment to increase the effectiveness of in situ chemical oxidation (ISCO) remediation of matrices contaminated by explosives and other toxic aromatic compounds with nitro substituents. The pretreatment step involves the injection or addition of a relatively inexpensive reducing... Read More
ua14-126 – Background The Conserve to Enhance (C2E) program was developed by the University of Arizona Water Resources Research Center (WRRC). C2E is a unique program that motivates consumers to use water more efficiently by linking water conservation efforts with environmental enhancements in their community and region. Since drought is becoming a major issue in the Southwest, there is a need to... Read More
ua13-072 – This technology consist of a sorbent that effectively removes perfluorinated compounds (PFCs) from water. The sorbent is a combination of two hydrophobic cationic polymers with structural modifications to enhance electrostatic and hydrophobic interactions with perfluorinated compounds. The polymers have the ability to remove PFCs in two ways: through ion exchange and hydrophobic... Read More
