Aminobenzene sulfonic acid-functionalized carbon nanotubes on glassy carbon electrodes for probing traces of mercury(II)

Jing Lv, Ying Tang, Liumei Teng, Dianyong Tang, Jin Zhang


This work reports on a new electrochemical sensing strategy for quantitative monitoring of inorganic mercury(II) in contaminated water by immobilization of poly(p-aminobenzene sulfonic acid)-functionalized single-walled carbon nanotubes on a glassy carbon electrode. The electrochemical behavior of the resulting sensor was assessed and optimized. Under optimal conditions, the sensor displayed good electrocatalytic responses to Hg2+ red­uction ranging from 1.0 μmol L-1 to 0.5 mmol L-1 with a detection limit of 0.5 μmol L-1. The selectivity against other potentially interfering ions and the applicability in contaminated water samples were also evaluated.
