Abstract
Para-ethyl-oxyethylamino-aniline or one of its salts is employed as a reagent for testing the presence of chlorine in the water of swimming pools. The reagent dissolved or dispersed in a polypropylene-glycol ethoxylate is coated on to a support. When the coated support is stirred into the water a pink color develops in the water if chlorine is present and the intensity of the color can be used to gauge quantitatively the amount of chlorine present.
