Thermal reactivation of ammonia-tailored granular

Thermal reactivation with CO 2 or NH 3 at temperatures higher than 700 °C effectively restored the perchlorate adsorption capacity of ammonia-tailored carbon In contrast, steam regeneration restored only a portion of the perchlorate adsorption capacity, and these distinctions were attributed to the change in surface chemistry that was induced by regeneration.
