(332f) Adsorption on NDMA on Biomass-Derived Activated Carbons in Lab-Scale Columns
In this study, biochars produced from pecan shells and local forestry waste were tested in a lab-scale column for adsorption of NDMA. Concentrations of carbon-14-labeled NDMA in well water obtained near a NASA rocket-test site were measured at regular time intervals over the course of the flow through the biochar-filled column for several adsorbents. Liquid scintillation counting was used for quantification to enable faster and most consistent results with smaller sample sizes. Data from the breakthrough curves was used to calculate column design parameters to estimate the cost of adsorption treatment.
