ABSTRACT:
Disclosed is a method of determining the presence of glycol in an aqueous solution comprising providing a container containing a mixture of potassium dichromate, a catalyst comprised of mercuric sulfate and silver sulfate, the mixture provided in an acidic solution. To the container is added a controlled volume of aqueous solution containing glycol. The mixture is permitted a time sufficient to change color, the time not being in excess of 15 minutes. The color is compared to a set of color standards to determine the presence of glycol in said aqueous solution.
