EUROLAB laboratory provides testing and compliance services within the scope of SM 4500-CL B standard. The iodometric method is suitable for measuring total chlorine concentrations greater than 1 mg/L in natural and treated water. Not valid for estuary or sea waters.
Chlorine will release free iodine from potassium iodide (KI) solutions at pH 8 or below. The liberated iodine is titrated with a standard sodium thiosulfate (Na2S2O3) solution with starch as an indicator.
Oxidized forms of manganese and other oxidizing agents interfere. Reducing agents such as organic sulfides also interfere. Although neutral titration minimizes the inhibitory effect of ferric and nitrite ions, acid titration is preferred as some combined forms of chlorine do not react at pH 7.
EUROLAB assists manufacturers with SM 4500-CL B test compliance. Our test experts, with their professional working mission and principles, provide you, our manufacturers and suppliers, the best service and controlled testing process in our laboratories. Thanks to these services, businesses receive more effective, high-performance and quality testing services and provide safe, fast and uninterrupted service to their customers.
