Abstract
En 中文
An easy and highly-sensitive electrochemical sensor for chlorophenols (CPs) was constructed based on the nanocomposite films of electrochemically-reduced graphene oxide-cationic pillar[6]arene (ErGO-CP6) using onestep potentiostatic electrodeposition method. Compared to the ErGO film, the ErGO-CP6 composite film added favourable electron transfer access and gave a better electrocatalytic performance of CPs oxidation because of the ErGO-CP6 synergy. This study selected 2-chlorophenol (2-CP, a typical CPs compound) as a model representative organic pollutant. The oxidation peak current of 2-CP was linearly proportional to the 0.01-39.5 mu M concentration range at optimal conditions, with a 0.005 mu M limit detection. The approach proposed in this study could conveniently determine the level of total CPs.
