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.
