Performance of new mesoporous carbon sorbent prepared from grape industrial processing wastes for malachite green and congo red removal

- Langmuir model and pseudo-second order kinetics described the sorption process.
- High sorption capacity for MG and CR were observed.
- Sorption mechanisms of MG and CR on the GWAC are discussed.
- Sorption of MG and CR onto GWAC were spontaneous and endothermic in nature.
- GWAC is a promising sorbent for the MG and CR removal from water.
