The method of ethylene glycol determination in flue gases is described
. Glycol under-goes sorption either on solid adsorbents such as silica
gel or activated carbon, or in bubbler absorbers filled with water. W
ater is the best for desorption of glycol from silica gel; in the case
of activated carbon methylene chloride doped with 5% of methyl alcoho
l is recommended. Limit of determination is 10-20 mg m(-3) depending o
n the sorbent used and the volume of air drawn through the sorbing tra
in.
