Previously reported data on CS2 adsorption by activated carbon
| Type of material | Reaction | Adsorption capacity | Temperature | Source | Reference |
|---|---|---|---|---|---|
| Zinc-carbon composite | Batch reactor | 124.3 mg of CS2/g | 30 °C | Hydrocarbon | This work |
|
Cu/CoSPc/Ce modified activated carbon (ACCu‑CoSPc‑Ce) |
Fixed-bed quartz reactor system |
Adsorption capacity of 17.39 mg of CS2/(g of activated carbon) |
20 °C | Gas | (Wang et al. 2014) |
| Activated carbons | Batch system |
The adsorption capacity of CS2 in damp gas is 60%–80% less than that in dry gas |
50 °C | Gas | (Wang et al. 2011) |
| Active carbon fiber (ACF) | Batch system |
The adsorption capacity of ACF is more extensive (72–104%) than that of GAC |
150 °C | Water | (Yang et al. 2006) |
| Ion-exchanged zeolites Y | Fixed-bed adsorption column |
The highest CS2 breakthrough adsorption capacity up to 44.8 mg/g |
20 °C | Air | (Chen et al. 2017) |
| Polyacrylonitrile (PAN)-based activated carbon fiber (ACF) | A fixed-bed glass reactor | The best breakthrough adsorption capacity of CS2 was 55.63 mgS/g when CO activated the ACF | Room temperature | N2 gas | (Li et al. 2020) |
| Hydrophobization of activated carbon fiber (ACF) using vinyltrimethoxysilane | Glass vacuum system | The adsorption selectivity is improved under humid conditions | 25 ℃ | N2 gas in dynamic conditions | (Xie et al. 2011) |
| Activated carbon modified with KOH and ethylenediamine | Glass vacuum system | The CS2 adsorption is improved | 30–60 ℃/0–30,000 Pa | – | (Guo et al. 2006) |
