Abstract
The potential of oxidized multiwalled carbon nanotubes as a fiber coating for solid-phase microextraction of carbendazim, thiabendazole, and thiophanate-methyl from aqueous solution has been investigated, and the mechanism of adsorption has been explored. When an analytical method combining SPME with high-performance liquid chromatography was applied to real environmental water samples, recoveries of the spiked compounds was 75.7–104.5%, the linear range was 5–500 ng mL−1, the squared correlation coefficients (r 2) were from 0.9978 to 0.9984, LOD were from 0.3 to 1.5 ng mL−1, and RSD were from 2.3 to 10.5%.
