Characterization, Functionalization, and Adsorption Behavior of Single-Walled Carbon Nanotubes towards Bisphenol A and 17 Β- Estradiol

<p>This study evaluated the environmental applications of single-walled carbon nanotubes (SWNTs) through the adsorption of representative endocrine disrupting compounds: bisphenol A (BPA) and 17 β-estradiol (E2). Initially, a protocol was developed to understand the effect of ultrasonication on the dispersion of SWNTs in water. The results of adsorption experiments have showed that BPA and E2 can be removed from water by adsorbing onto SWNTS, however, the two compounds vary in their affinity towards adsorbent. Alteration of water chemistry failed to significantly affect the adsorption behavior. Acid functionalization of SWNTs decreased the BPA adsorption while minimally affecting E2 adsorption. Adsorption mechanism was understood by evaluating thermodynamics, activation energy, kinetics and internal energy.</p>
