AB  - Chlorinated volatile organic compounds (VOCs), of which dichloromethane (DCM) has 
      become one of the main components because of its extensive use and strong 
      volatility, are recognized as extremely hazardous and refractory pollutants in 
      the atmosphere. The efficient treatment of DCM is of great significance to the 
      protection of environment and human health. In this work, the strategy of DCM 
      capture with deep eutectic solvents (DESs) with different hydrogen bond acceptors 
      (HBAs) and hydrogen bond donors (HBDs) was proposed and systematically 
      investigated. The experimental results show that tetrabutylphosphonium chloride: 
      levulinic acid ([P(4444)][Cl]-LEV) presents the most excellent DCM absorption 
      capacity among all DESs studied and considerable capacity in [P(4444)][Cl]-LEV 
      (1:2) with 899 mg DCM/g DES (5.58 mol DCM/mol DES) at 30  degrees C and DCM partial 
      pressure of 0.3 bar can be achieved. The microscopic absorption mechanism is 
      explored by (1)HNMR and FT-IR spectra as well as quantum chemistry calculations, 
      indicating that the absorption is a physical process. The interaction energy 
      analysis suggests that the greater the interaction energy between DES and DCM, 
      the greater the saturated absorption capacity of DCM. The hydrogen bond (HB) 
      contributes most to the weak interaction between DCM and HBA/HBD, and both HBA 
      and HBD play an important role in the absorption of DCM.
