Phenolic compounds, as highly toxic pollutants, can cause great harm to human beings and the environment even at very low concentrations. Therefore, simultaneous detection of multiple phenolic pollutants is critically valuable for environmental monitoring. Here, an electrochemical sensor based on a glassy carbon electrode (GCE) modified by nanoporous gold (NPG) was successfully developed determination including phenol (Ph), hydroquinone (HQ), catechol (CT), o-nitrophenol (ONP), which realized not only sensitive individual each pollutant but also these four pollutants. For detection, limits Ph, HQ, CT, ONP were 0.85, 0.17, 0.19, 1.30 μM well sensitivities 0.24, 1.17, 1.08, 0.16 μA −1 cm −2 , respectively. Additionally, NPG/GCE exhibited good stability anti-interference capability. The recovery rates in seawater samples wastewater ranged from 94.64% 105.87%. These results indicated that prepared may be ideal choice reliable
