✦ Synopsis

The potential of carbon nanotubes (CNTs) as a novel sorbent for extraction of dicamba, a highly polar acidic herbicide, from aqueous samples was evaluated. The sorption capacity of CNTs increases remarkably with decreasing sample pH. The solution of ACN and ammonia (80:20 v/v) was found to be the most effective as the eluent for desorption from a 0.2 g CNT cartridge. The method was tested for river water samples with the LOD of 2 lg/L (for 100 mL sample) and compared with C 18 bonded silica.

Carbon nanotubes (CNTs) were prepared by ethylene decomposition on an Fe /Al O catalyst in a fluidized bed reactor. 2 3 Their gross defects at different growth periods are evaluated by using a combination of SEM, TGA and Raman spectroscopy. The initially grown CNTs have a much lower thermal stabili
