Abstract
⺠We prepared dithizone modified silica-coated magnetic Fe3O4 nanoparticles. ⺠A method of magnetic SPE-ICP-OES was proposed for trace heavy metal analysis. ⺠The developed method is simple, highly selective and sensitive. ⺠It is suitable for the analysis of samples with large volume and complex matrix. ⺠The adsorption mechanism was investigated by FT-IR and XPS.
