Chlorine dioxide concentration in the water disinfection residual chlorine dioxide detection CLO2 test kit 0.05 ..

0.05-2.0mg / l of chlorine dioxide test kit is widely used in water laboratories, hospitals, chemical industry, printing and dyeing water quality testing, while chloride is also commonly used as a disinfectant that eliminates bacteria, Commonly used in drinking water, but chlorine itself is kind of toxic substances, high levels of health and the environment is also a certain hazards. State chlorine content in drinking water is limited to: 0.02-0.8mg / l. Chlorine dioxide test kit for use Specification Description: Product Specifications: 0.05-2mg / l detection times: 30 times / box Shelf Life: 2 years Storage: room temperature, a cool dry place Instructions: Test Range: 0.05-0.10-0.25-0.50 -0.75-1.00-1.50-2.00mg / L Test Method: colorimetric with test tube water rinse twice with water and then tick kind to the tube, add chlorine dioxide reagent a small glass spoon, shake until the reagent is completely dissolved let stand 3 minutes, from top to bottom with the standard color card visual colorimetric, and the tube was similar tone color is the water sample chlorine dioxide content (mg / l), as compared with monocular color observation, the better. Common interference: 1, PH value. It should be controlled at 5-8. 2, oxidant: bromo, iodo, acting amines, amine iodine, ozone, hydrogen peroxide, dichromate, manganese oxide and the like. 3, reducing: nitrite. 4, if the water alkalinity exceeding 250mg / l, acidity than 150mg / l, the measurement process will be unstable measurements, the sample color will disappear or very light. Diluted HCl or Na0H sample neutralization reaction, solve this problem. Packing Details: chlorine dioxide reagent 4 package, a test tube, a dropper, a colorimetric card, glass spoon 1.
