Rapid growth of production of glycols and their derivatives, especially methyl and ethyl esters, and wide use of these substances in various branches of the national economy (1) inevitably necessitate analytical monitoring of their content in waste waters and various water bodies. The authors studied the scope of gas-chromatographic determination of microamounts of glycols and their esters in aqueous media at the sanitary standards level (10/sup -5/%) using activated charcoal for their adsorption concentration from aqueous solutions, desorption from the charcoal by ethanol, and evaporationconcentration of the alcoholic solutions. The quantitative concentration characteristics were studied with reference to ethylene glycol, propylene glycol, diethylene glycol, dipropylene glycol, triethyleneglycol, tripropylene glycol, tetraethylene glycol, ethylcellosolve, ethyl carbitol, and monoethyl ester of triethylene glycol.
