“…Most authors (Cai et al 2003;Basheer et al 2005;Adomaviciute et al 2008) agree on the positive effect of the addition of NaCl or Na 2 SO 4 to the sample for the extraction efficiency of most compounds; however, some discrepancies have been found and no direct relation between extraction efficiency and salt addition has been pointed out in some cases (Carrillo and Tena 2005;Du et al 2005). In this experiment, 1 g Na 2 SO 4 or NaCl was added to the 10 mL aqueous solution to test the salting out effect.…”

A novel solid-phase microextraction (SPME) fiber was prepared by coating multiwalled carbon nanotube (MWCNTs) on a stainless steel wire, and its characteristics were studied. To evaluate the MWCNTs coating, the fiber was used for the extraction of some organochlorine pesticides (OCPs) from water samples by Headspace SPME (HS-SPME) mode. Potential factors affecting the extraction efficiency such as extraction time, extraction temperature, agitation, ionic strength, desorption temperature, and time were also optimized. Several experiments were carried out by water spiked with target compounds to evaluate the analytical characteristics of the proposed method under optimized conditions. The linearity was from 0.1 to 10 ug/L with the linear correlation coefficients (r) ranging from 0.9956 to 0.9995. The limits of detection (LOD, S/N ¼ 3) for these pesticides were between 0.43 and 2.13 ng/L and the precision (RSD, n ¼ 5) was 2.53-12.25%. When this method was applied for the spiked real river sample, the relative recoveries ranged from 72.4% to 134.7% for the tested OCPs.

“…The coating of CNTs with organic glue or by epoxy resin was also used by Chen et al (Chen et al, 2009) who used Nafion as the polymer to immobilize MWCNTs on the fiber for the determination of polar aromatic compounds in natural water samples. Similarly, Adomaviciute et al (Adomaviciute et al, 2008) employed an epoxy glue to deposit CNTs on a modified SPME fiber to determine traces of aromatic hydrocarbons in petrol station wastewaters.…”
