BS 6337 discusses general methods of chemical analysis. BS 6337-4 is the fourth part of the BS 6337 multi-series and discusses a method for the determination of chloride ions by potentiometry.
BS 6337-4 is applicable to test solutions having chloride ion concentrations, expressed in milligrams per litre, of between 1 and 1 500.
Note: The preparation of the test solution and any modifications to the general procedure should be dealt with in the specific International Standard for the chemical product to which the method is to be applied.
BS 6337-4 on determining the chloride ions in solutions prepared from chemical products for industrial use is useful for:
The method in BS 6337-4 may be used to determine the total chlorine contained in chemical products after transforming it, if necessary, into chloride ions by a suitable process. The method in BS 6337-4 has an absolute error, expressed as milligrams of chlorine, of 0,1 to 1 mg, according to the concentration of the standard volumetric solution used.
BS 6337-4 provides you with a general potentiometric method for the determination of chloride ions in solutions prepared from chemical products for industrial use. Under certain conditions, it is possible to determine bromide and iodide ions either simultaneously or separately. If chloride only is to be determined, bromide and iodide may be eliminated by the method in BS 6337-4.
