Compound surfactants were added to aqueous LiBr solution in static pool setup to study their effect on water vapor absorption of aqueous LiBr solution. 1- Octanol

2- Octanol

2- Ethyl- 1 - hexanol

and 1 - Hexanol were added to 60w LiBr solution individually and in the mixture form of two surfactants. The experimental result shows that the effect of compound surfactants is near to the better one between them

for example

1 - Octanol is the best one during these four additives

the effect of any other additive mixed with 1 - Octanol is near to the effect of 1 - Octanol alone.
