The method specified is applicable to concentrations in the range 0,02 to 15 mg/l. The ions and compounds listed in the table, if present single or in combination at concentrations above the specified limiting concentration, interfere with the method. The presence of aldehydes may give lower values because of the formation of cyanohydrin.
