文摘
- •
Glassy carbon electrode surface was modified with NiO for lead(II) and cadmium(II) detection.
- •
Surface detection effect was evaluated by detection limit, sensitivity and linear relativity.
- •
Balls NiO modified electrode showed better electrochemical detection ability.
- •
Lager BET surface area of NiO made electrode surface excellent electron transfer capacity.
- •
Balls NiO modified electrode exhibited superior adsorption capacity and detection stability.
