Peak areas obtained with the MWCNTs/NaDC fiber and commercial PDMS/DVB fiber for phenols. The extraction of MWCNTs/NaDC fiber and commercial PDMS/DVB fibers for phenols were under the optimized conditions. Extraction time: 50 min; stirring speed: 1100 rpm; NaCl concentration: 36% (w/v); concentration of phenols: 100.0 ng/mL for Phenol, 4-NP, 2-NP, 2,4-DMP and 2,4-DCP. Error bars show the standard deviation of the mean (n = 3)
