Abstract Development of nanostructured materials has received tremendous attention nowadays due to their unique properties and efficacious in wide range of applications. Herein, we present a facile synthesis of ZnSe–CdSe/SiO2 core–shell nanomaterial for pollutants monitoring and environmental remediation purposes. The utility of ZnSe–CdSe/SiO2 core–shell nanomaterial was explored toward electrochemical detection and adsorptive removal of copper ions from aquatic system. Experimental results reveal that both electrochemical detection and adsorption of Cu(II) using ZnSe–CdSe/SiO2 nanomaterial strongly depends on the solution pH, with an optimum pH of 5. Based on the results, the amperometric sensor based on ZnSe–CdSe/SiO2 core–shell nanomaterial modified electrode exhibited a detection limit of 50 μg L−1. Moreover, ZnSe–CdSe/SiO2 core–shell nanomaterial as adsorbent demonstrated high uptake capacity equals to 126.25 mg g−1. Thus, ZnSe–CdSe/SiO2 core–shell nanomaterial can be employed as promising material for several environmental remediation purposes.
