  • AMINE FUNCTIONALIZED CHITIN FOR REMOVING SUBSTANCES FROM SOLUTIONS
    Publication number: 20220176346
    Abstract: In one embodiment, a method of removing a substance from a solution by adsorption includes: interfacing a delivery component containing a quantity of amine functionalized chitin (AFC) compound as an adsorbent AFC compound with the solution containing the substance as an adsorbate substance; mixing the adsorbent AFC compound and the adsorbate substance in the solution for a period of time; and removing a mixture of the adsorbent AFC compound and at least a portion of the adsorbate substance from the solution.
    Type: Application

  • AMINE FUNCTIONALIZED CHITIN FOR REMOVING MUNITIONS COMPOUNDS FROM SOLUTION
    Publication number: 20220033530
    Abstract: The invention is a renewable adsorbent material, amine-functionalized chitin (AFC) that can remove the following munitions compounds from solution while providing a concentration-dependent color change: NTO, DNAN, and TNT. Adsorption of the munitions constituents can be adjusted by pH; neutral pH provides maximum adsorption. NTO can desorb from the AFC at pH levels of 2 and 12; DNAN and TNT remain attached to AFC once adsorbed.
