文摘
- •
Hazardous dyes were removed using a nano γ-Fe2O3 based magnetic cationic hydrogel.
- •
Equilibrium was established within 5 min exhibiting fast sorption kinetics.
- •
Sorption capacity was high outcompeting other sorbents in the literature.
- •
Sorbent was highly reusable over 30 consecutive sorption–desorption cycles.
- •
Sorbent is superparamagnetic which allows its convenient magnetic separation.
