作者： Yiming Tian Pingsheng Zhong Kai Zhou Lufei Zheng Jiali Ren Hunan key laboratory of Forestry Edible Resources safety and Processing， Hunan key laboratory of Grain-oil Deep Process and quality control， Central South University of Forestry and Technology Institute of quality Standard and Testing Technology for Agro-Products of CAAS

The accumulation of heavy metals in mushrooms has presented a significant risk to human health， underscoring the importance of devising a portable and cost-effective method for detecting heavy metals. Thus， we have developed an electrochemical sensor based on 3-dimensional highly reduced graphene oxide (3D-HRGO) in conjunction with Fe3O4nanoparticles， enabling the simultaneous quantification of Cd2+， Pb2+， Cu2+， and Hg2+. The 3D-HRGO/Fe3O4nano-particles material prepared in this study was characterized and confirmed by multiple techniques， then dispersed in a simple and environmental dispersant， consist of 75% ethanol and 0.1% Nafion， and coating on a glass carbon electrode (GCE) to preparing a 3D-HRGO/Fe3O4/GCE sensor. The limit of detection (LOD) of 3D-HRGO/Fe3O4/GCE sensor for Cd2+， Pb2+， Cu2+， and Hg2+in simultaneous detection were 0.2 μg/L， 0.6 μg/L， 0.6 μg/L， and 0.9 μg/L， respectively. The sensor demonstrates exceptional stability， reproducibility， anti-interference， and recovery rate. Furthermore， the electrochemical sensor was employed to detect heavy metals in actual mushrooms and validated through conventional methodologies. This study represents the pioneering utilization of 3D-HRGO/Fe3O4as a foundational material for an electrochemical sensor capable of simultaneous detection of multiple metals， thereby advancing the progress of on-site and expeditious detection techniques.
