Methods of measuring free and total chlorine content in solutions are provided without lowering the pH of the solution to the acid range by measuring the concentration of chlorine in a solution containing chlorine and water and a sufficient amount of proton donating compound to permit electrochemical measurement of the chlorine. In one embodiment, the method further comprises modifying the composition to contain a proton donating compound. An additional potassium iodide reagent is added when total chlorine content is measured. Stable aqueous reagent solutions useful in automated chlorine analyzers which contain sodium bicarbonate, a base, and water or borax, water, and acid are also described. Finally, apparatuses for detecting the level of chlorine in water samples utilizing an automated chlorine detector, a cartridge having a solid proton donating compound, and optionally a standpipe are discussed. <IMAGE> |
