Abstract: A headspace solid-phase microextraction (SPME) method using a stainless steel wire electrophoretically coated with dodecylsulfate modified multiwalled carbon nanotubes was used for the gas chromatographic (GC) determination of polycyclic aromatic hydrocarbons (PAHs) in aqueous samples. Electrophoretic deposition was easily carried out from an aqueous sodium dodecylsulfate medium. The effects of various parameters on the efficiency of SPME process, such as extraction time, extraction temperature, ionic strength, desorption time, and desorption temperature were studied. Under optimized conditions, the detection limits for the various PAHs studied varied from 0.03 to 0.07 ng mL−1. The inter-day and intra-day relative standard deviations at a 10 ng mL−1 concentration level (n = 7) using a single-fiber were from 5.5 to 9.7 and 4.1 to 8.5 %, respectively. The fiber-to-fiber RSD% (n = 3) was between 7.3 and 11.1 %. The linear ranges were between 0.1 and 100 ng mL−1. The method was successfully applied to the analysis of a real sample with the recoveries from 88 to 105 % for 5 ng mL−1 and 89 to 101 % for 0.5 ng mL−1 samples.

Adsorption of cadmium(II) from aqueous solution by surface oxidized carbon nanotubes
TL;DR: In this article, carbon nanotubes (CNTs) were oxidized with H2O2, KMnO4, and HNO3, and the experimental results suggest that cadmium(II) adsorption capacities for three kinds of oxidized CNTs increase due to the functional groups introduced by oxidation compared with the as-grown CNT.
