文摘
- •
Simultaneous ultrasonic-assisted adsorption of heavy metal ions was studied on GO.
- •
Various isotherm models and kinetic models were studied.
- •
CCD was applied to evaluate the interactive effects of adsorption variables.
- •
This new adsorbent exhibits high adsorption efficiency and, very good selectivity.
