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.

A method of removing a substance from a solution by adsorption, the method comprising:
- 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.
A method of removing a perfluoroalkyl or polyfluoroalkyl substance (PFAS) from a solution, the method comprising:
- interfacing a delivery component containing a quantity of amine functionalized chitin (AFC) compound as an adsorbent AFC compound with the solution containing the PFAS as an adsorbate PFAS;
- mixing the adsorbent AFC compound and the adsorbate PFAS 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 PFAS from the solution.
A method of removing a munitions compound from a solution, the method comprising:
- interfacing a delivery component containing a quantity of amine functionalized chitin (AFC) compound as an adsorbent AFC compound with the solution containing the munitions compound as an adsorbate munitions compound;
- mixing the adsorbent AFC compound and the adsorbate munitions compound 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 munitions compound from the solution.
