"Complex" Pyridine [not simple PDADMAC.] Yael Mishael – Clay Polymer Sorbents for the Removal of Organic Micro-Pollutants (TTM:2876)– Prof. Mishael developed a patented clay based ‘pyridine’ composite to remove organic pollutants with a higher efficiency then activated carbon. The composite is cheap to produce yet highly effective in removing drugs, herbicides and pesticides. Patent Position: Yissum Online: Below thoughts were edited and approved by Yael Mishael: The complex pyridine based polymer is ‘designed’ for catching micro pollutants @ ng/Liter concentrations (single molecule - pharmaceuticals, herbicide, pesticide), but there are no regulations in place for treatment of micropollutants from waste water.  So there is no incentive for companies/municipalities to add expensive capex to treat this wastewater (capex for pumps, filtration columns etc – irrespective of adsorption resin). There is not really a need for filtering freshwater (tap water) through a complex resin since freshwater is not tested for micro pollutants and is not likely to have this and again there is no regulation for this.   On the other hand the simple ‘PDADMAC’ polymer can be used for filtering any dissolvable organic matter (humeric/muddy), and can be used for clearing up opaque fresh water prior to drinking or treated wastwater. So the results are clearly visible and can be used in municipalities and private home filtration systems, and it was found to be more efficient and more cost effective in purifying organic matter than granulated activated carbon.

The research group in Bioelectrochemistry and Biosensors of the University of Alcalá in collaboration with the Textile Industry Research Association (AITEX) has developed an electrochemical sensor of magnesium (Mg2 +) and a construction method based on the formation of a polymeric three-dimensional network that allows the entrapment / immobilization of a selective indicator for Mg2 +, eriochrome black T, by the use of a crosslinking agent and a polymer. The combination of these three reagents allows the construction of the sensor on any conductive surface, avoiding the electro polymerization of the indicator. The resulting sensor allows to measure MG2 + in any type of samples, without the need to add organic salts, additives or organic solvents. The quantification of Mg2 + is done directly by incubating the sensor in the sample containing the analyte, resulting in a modification of the amperometric signal proportional to its concentration. This method has many applications especially in health and biomedical sector since Mg2 + participates in such important activities as neuronal, neuromuscular transmission, or regulation of blood pressure and plays a key role in various pathologies such as vascular and migraines headache. The group is looking for companies in the agro-food, bio-sanitary and environmental sectors, with the aim of reaching technical collaboration agreements, commercial agreements or patent licenses.
