摘要

As an efficient modified electrode material for the detection of heavy metal ions, bismuth nanoparticles (BiNPs) were loaded on cobalt ferrite (CoFe _(2) O _(4) ), a unique magnetic photocatalytic material, to fabricate a highly sensitive sensor. The obtained BiNPs@CoFe _(2) O _(4) nanocomposites showed excellent adsorption and electrical conductivity using a Square Wave Anodic Stripping Voltammetry (SWASV) detection method. Under optimized conditions, the BiNPs@CoFe _(2) O _(4) /GCE sensor could simultaneously determine Pb ~(2+) and Cd ~(2+) , with detection limits of 7.3 and 8.2 nM, respectively. In addition, the BiNPs@CoFe _(2) O _(4) exhibited acceptable reproducibility and good stability, which indicated great potential for the detection of heavy metal ions in reality.
