EM Quant® Chloride Test, Catalog No. 10079Test strips for the detection and semi-quantitative determination of chloride ions 1. MethodChloride ions react with silver ions, decolorizing red-brown silver chromate. The concentration of chloride is measured semiquantitatively by visual comparison of the reaction zones of the test strip with the individual color rows of a color scale. 2. Measuring Range and Number of Determinations
1 for measurement of concentrations>3,000mg/l Cl– see section 7 4. ApplicationsEM Quant® analytical test strips are designed for preliminary tests and for the determination of graduated concentration ranges. The test is particularly recommended for the determination of the chloride content in conjunction with COD determination. Sample material:Wastewater 5. Influence of foreign substancesThe concentrations of foreign substances given in the table lie below the limit at which the determination is interfered with. Concentrations of Foreign Substances ppm (mg/l)
6. Reagents and auxiliariesStore original sealed packs in refrigerator. Other reagents and accessories:Universal indicator strips pH 0-14, Cat. No. 9590 6. Preparation· The pH of the sample solution must be within the range 5-8. Adjust, if necessary, with sodium hydroxide solution or nitric acid. 7. Procedure
· After 1 minute compare color pattern of the reaction zones with the color rows on the label. Determine which row color pattern coincides most exactly and read off the corresponding concentration value. If an exact color match cannot be achieved, estimate an intermediate value.
