BS 6068-2.19 is the 18th section of the BS 6068 standard that specifies a method for the determination of cyanides, as cyanogen chloride in water.
The method described in BS 6068-2.19 is applicable for the determination of cyanogen chloride concentrations in the range 0,02 to 15 mg/l.
The ions and compounds listed in the table, if present singly or in combination at concentrations above the specified limiting concentration, interfere with BS 6068-2.19.
The presence of aldehydes, e.g. formaldehyde, may give lower cyanide values because of the formation of cyanohydrin.
BS 6068-2.19 on the Physical, chemical and biochemical methods are useful for:
Cyanides may be present in water as hydrocyanic acid (prussic acid), cyanide ions, and complex cyanides. They may be determined as total cyanide or as easily liberate cyanide, if cyanide compounds are chlorinated, cyanogen chloride (ClCN) is produced, and this compound has to be determined separately.
BS 6068-2.19 provides methods for characterizing water quality based on physical, chemical, and biochemical measures and methods for determining the cyanogen chloride present in raw water.
BS 6068-2.19 provides you with apparatus, sampling, transport, storage, and preparation of test pieces, preparation of reagents and apparatus, pre-treatment of test pieces, test procedure, and much more.
The test methods and procedures provided by BS 6068-2.19 assist you in the determination of cyanogen chloride content in water and ensure reducing the risk of severe health issues.
With obedience and compliance to BS 6068-2.19, you can enhance the efficacy of the water and manufacture a standardized product.
