This standard specifies the use of cadmium reagent 2B Spectrophotometric method, spectra-trophotometry to determine the concentration of silver in water. It is suitable for wastewater discharged from photosensitive material production, silver plating, smelting and other industries and surface water contaminated with silver. The method generates a purplish-red complex between silver ions and cadmium reagent 2B to determine Absorbance at a wavelength of 554 nm. The measurement range is 0.01 to 0.8 mg/L, and the measurement range can be expanded by appropriately condensing or diluting samples. This standard is used for the determination of silver content in water quality monitoring.
