AB  - This study investigates the effect of using water as a low-viscosity component in 
      ternary amine-based deep eutectic solvents (DESs) on the physicochemical 
      properties, thermal stability, and CO2 absorption capacity of the resulting DESs. 
      It should be emphasized that water is a component of the ternary DES. The effect 
      of water content in the DES, type of hydrogen bond acceptors (HBAs), hydrogen 
      bond donors (HBDs), and HBA:HBD ratio on the above parameters was investigated. 
      Moreover, the effect of temperature and pressure on the CO2 absorption capacity 
      of DESs was predicted using the predictive model COSMO-RS. This model was also 
      used to predict the CO2 solubility in the DESs and the results were compared with 
      the experimental values. The results showed that the addition of small amounts of 
      water, e.g., 5 and 10 wt% during preparation, can significantly decrease the 
      viscosity of the resulting DESs, up to 25% at room temperature, while maintaining 
      the high CO2 absorption capacity and high thermal stability. The ternary DESs 
      based on MEA exhibited a high CO2 absorption capacity of 0.155-0.170 g CO2 / g 
      DES. The ternary DESs were found to be thermally stable with a decomposition 
      temperature of 125 degrees C, which promotes the use of such solvents in post-combustion 
      capture processes. Finally, COSMO-RS proved to be a suitable tool for qualitative 
      prediction of CO2 solubility in DESs and demonstration of trends related to the 
      effects of temperature, pressure, molar ratio, water content, HBD and HBA on CO2 
      solubility.
