摘要: An electrochemical sensor toward nitrite based on Ni foam supported nickel phosphide (NiP/NF) electrode was successfully fabricated via an in situ electrodeposition strategy. The sensor has exhibited great electrochemical detection ability with a sensitivity of 1.56 x 10(-4) mA mu M-1, a linear range from 0.1 to 4000 mu M and a detection limit of 0.01 mu M (s/n = 3). Moreover, good stability of the electrodeposited electrode can be ascribed to the in situ growth of NiP onto Ni foam to achieve a binder-free electrode. The good recovery achieved for nitrite detection in several water samples also reveals its promising practicality.
