Adsorption of Cu (II), Mn (II) and Zn (II) by Spirodela polyrhiza (L.) Schleiden: Equilibrium, kinetic and thermodynamic studies

Highlights
- S. polyrhiza biomass as a new adsorbent.
- Adsorption isotherm follows Langmuir model.
- Adsorption is feasible, spontaneous and exothermic.
- Multi-metal ion adsorption shows antagonistic nature.
