摘要	Fe3O4-N-[(3-Trimethoxysilyl)propyl]ethylenediamine triaceticacid trisodium (Fe3O4-TMS) has been synthesized by TMS adsorb to the surface of Fe3O4. Energy dispersive spectrometer (EDS) was used to characterize Fe3O4-TMS. The results of EDS indicate that TMS is modified on the surface of Fe3O4 successfully. The effects of initial concentration, pH, and coexist ions on the equilibrium adsorption capacities of strontium ion were investigated comprehensively. Removal of Sr2+ could reach 100% when initial concentration of Sr2+ is 1.0 mmol/L. The effect of pH conforms to S curve. Equation of the curve is q(Sr) = 0.08104 - 0.09012/(1 + exp((pH - 2.92707)/0.2995)). Correlation coefficient is equal to 0.9987. Sodium and calcium ions suppress the adsorption of strontium ion. Complexation and ion exchange maybe main adsorption mechanism.
