Full TextAbstract
This paper reports the preparation of multiwalled carbon nanotubes/4,4’-dihydroxybiphenyl (MWCNTs-DHB) nanolayered composite as a new modifier for modification of carbon paste electrode (CPE/ MWCNTs-DHB). CPE/MWCNTs-DHB shows linear responses for phenol in the concentrations range of 0.04– 220 μM with a current sensitivity of 0.67 μA μM???? 1 and a detection limit of 8.0 nM (S/N=3). The electrode shows high selectivity, good repeatability (RSD=4.1%), excellent reproducibility (RSD=3.5%), and acceptable stability (91.2% over one-month storage). Moreover, the modified CPE exhibits appreciable recoveries (93.0– 104.0%) indicating its acceptable performance for determination of phenol in tap and river water samples.
