摘要：
We present a study on the synthesis, characterization and application of a pyridine-functionalized magnetic mesoporous silica material (called Py-Fe3O4@MCM-41) as an adsorbent for the solid phase extraction of trace quantities of lead and copper ions. The modified Fe3O4@MCM-41 can be easily separated from an aqueous solution by applying an external magnetic field. Effects of pH, amount of functionalized Fe3O4@MCM-41, extraction time, type and quantity of eluent, desorption time, and interfering ions on the extraction efficiency were evaluated and optimized. Lead and copper ions were then quantified using a flame atomic absorption spectrophotometer. Under the optimized conditions, the detection limit for lead and copper ions was 0.1 mu g L-1 and 0.08 mu g L-1, respectively and the maximum adsorption capacity of the synthesized sorbent for lead and copper ions was 287 mg g(-1) and 194 mg g(-1), respectively. The Py-Fe3O4@MCM-41 sorbent was characterized by thermogravimetric analysis, differential thermal analysis, transmission electron microscopy, Fourier transform infrared spectrometry and X-ray diffraction.
