Abstract
The paper presents new non-ionic deep eutectic solvent (DES) composed of natural and non-toxic
components i.e. guaiacol, camphor and levulinic acid in 1:1:3 molar ratio as a promising absorbent for removal
of selected volatile organic compounds (VOCs) including dichloromethane, toluene, hexamethyldisiloxane and
propionaldehyde from model biogas.
The affi nity of DES for VOCs was determined as vapour-liquid coeffi cients and the results were compared
with several well-known DESs based on quaternary ammonium salt as well as n-hexadecane and water. For new
DES, the absorption process was carried out under dynamic conditions.
The results indicate that non-ionic DES has high affi nity and capacity for VOCs being comparable to
n-hexadecane. In addition, absorbed VOCs could be easily desorbed from DES using activated carbon and
absorbent could be re-use minimum five times without signifi cant loss of absorption capacity
期刊介绍：
Archives of Environmental Protection is the oldest Polish scientific journal of international scope that publishes articles on engineering and environmental protection. The quarterly has been published by the Institute of Environmental Engineering, Polish Academy of Sciences since 1975. The journal has served as a forum for the exchange of views and ideas among scientists. It has become part of scientific life in Poland and abroad. The quarterly publishes the results of research and scientific inquiries by best specialists hereby becoming an important pillar of science. The journal facilitates better understanding of environmental risks to humans and ecosystems and it also shows the methods for their analysis as well as trends in the search of effective solutions to minimize these risks.
