Amino-functionalized silica magnetite nanoparticles for the simultaneous removal of pollutants from aqueous solution

- New functionalized magnetic sorbent was synthesized by the assistance of ultrasound.
- Sorbent can be regenerated and recovered easily by magnetic separation.
- Fast simultaneous removal of RB5 and SDBS was achieved for the first time.
- Pseudo-second-order model was fitted well for the kinetics of adsorption.
- The rate constant of adsorption for SDBS was higher than RB5.
