Heavy solvents (DEHA and PDMS) and water were assessed for the absorption of four VOC.
- class="label">•
A simple and timesaving experimental procedure was developed.
- class="label">•
Partition and mass-transfer coefficients were deduced from the experiments.
- class="label">•
The two organic solvents tested, especially DEHA, exhibited rather good affinity with all VOC.

The liquid-film coefficient was 500% higher in PDMS and 30% higher in DEHA than in water.
